The cost of LASIK and PRK can vary significantly depending on the doctor or surgeon you choose and other factors such as location, type of equipment used, and the complexity of your case. Generally speaking, LASIK may be the slightly cheaper of the two procedures.
On average, LASIK can range from $2,000 to $4,000 per eye depending on these factors, while PRK may be a little more expensive and can range from $2,000 to $5,000. It is important to note that even though PRK is a more involved procedure, it is still a safer option for those individuals with thin corneas or dry eyes since there is no cutting of tissue with PRK.
It is recommended to speak to your eye doctor or a LASIK surgeon to determine which procedure is best suited for you and to give you an accurate cost estimate that takes into account the services and treatments you will receive.

Does PRK last longer than LASIK?
The duration of the results from PRK and LASIK can be different for each individual, so there is no definitive answer as to whether one procedure typically lasts longer than the other. However, in general, PRK may result in longer-lasting changes to the eyes than LASIK.
While, in most cases, the changes made through LASIK tend to hold up well short-term, the use of a laser to make the necessary cuts carries the risk of creating irregularities in vision quality that may need to be addressed in the future.
PRK avoids these risks of using a laser, and generally, the vision results from PRK can last from 10 to 15 years, although every individual will respond differently. In addition, PRK does not use any cuts or manipulations that could cause complications with long-term effects.
Do doctors recommend LASIK or PRK?
Doctors may recommend either LASIK or PRK, depending on the individual’s condition and preferences. LASIK, or laser-assisted in situ keratomileusis, is a surgical procedure that involves reshaping the cornea with a a laser to improve vision.
PRK, or photorefractive keratectomy, is a type of laser eye surgery which involves removing the outer layer of the cornea and then reshaping underlying tissue using a laser. Both procedures can improve near and farsighted vision and reduce the need for eyeglasses or contact lenses.
When considering which procedure is best for a patient, doctors typically take into account the size and shape of the cornea, the thickness of the corneal tissue, and the amount of correction needed.
The patient’s preferences are also taken into consideration. Both LASIK and PRK can be successful procedures, and most patients report improved vision after the procedure.
Generally, doctors recommend that patients with larger corneas and deeper pockets of tissue are better suited for LASIK, while PRK may work better for those with curved corneas or thin corneal tissue.
In some cases, a doctor may recommend that a patient have a combination of both LASIK and PRK surgery in order to get the best results.
Ultimately, the decision of which procedure to have is best made in consultation between the patient and their doctor. They can weigh the advantages and disadvantages of both LASIK and PRK and decide which procedure is best for that individual’s needs.
Why do PRK instead of LASIK?
PRK (photorefractive keratectomy) is a refractive surgery procedure used to improve vision by treating the cornea of the eye. It is most commonly used to treat myopia (nearsightedness), astigmatism and hyperopia (farsightedness).
The main difference between PRK and LASIK is the way the cornea is prepared for the procedure. During PRK, a thin layer of the cornea’s surface is removed and the laser treatment is applied directly to the exposed cornea tissue.
On the other hand, during LASIK, a flap is created on the surface of the cornea to access the underlying tissue that is being treated by the laser.
Due to the different ways these procedures prepare the cornea for treatment, some pros and cons should be considered before deciding on a procedure for improving vision. PRK is preferred over LASIK for certain individuals, especially those with specific conditions such as dry eyes and thin corneas.
It is also the preferred procedure for people with higher levels of myopia, as well as those who are involved in dangerous professions or activities, such as contact sports, where the risk of infection after surgery can be heightened.
PRK also has fewer risks and side effects than LASIK. For instance, patients don’t experience any blurring or halos around lights that can sometimes occur with LASIK. Additionally, some patients report fewer dry eyes with PRK than they experience after LASIK.
In conclusion, PRK is the preferred procedure for certain individuals, such as those with higher levels of myopia, or those involved in activities with a higher chance of infection. Additionally, PRK usually has fewer risks and side effects than LASIK, and a quicker recovery period.
Therefore, depending on the individual’s condition, PRK might be a suitable alternative for vision correction instead of LASIK.
How long does it take to get 20 20 vision after PRK?
The amount of time it takes to get 20/20 vision after PRK can vary depending on the individual. In most cases, it takes 3-6 months to see the best possible results. However, this timeline can be expedited or delayed depending on how fast the individual’s eyes heal, how well they follow their doctor’s instructions, and how quickly they adapt to their new vision.
For example, some people who have had PRK may see their clearest vision within the first couple of weeks after the procedure.
One way to ensure a fast recovery is to stay diligent throughout the recovery period. Taking medications on schedule and following any other doctor’s orders are essential for a fast recovery process.
Additionally, protecting the eyes from dust, smoke, or strains of light or wind can also support the healing process.
Overall, the amount of time it takes to get 20/20 vision after PRK depends on the individual. While many people start to see results after just a few weeks, some may take as long as six months to get their clearest vision.
Taking appropriate steps during recovery—like following doctor’s orders and shielding their eyes from dust and smoke—can help expedite the process.
What age is for PRK?
PRK, or photorefractive keratectomy, is a type of corrective laser eye surgery that is used to correct nearsightedness, farsightedness, and astigmatism. It is most commonly used for individuals over the age of 18 who require vision correction, although some Laser Eye Centers may set their own lower age limits for eligibility.
PRK is an appropriate vision correction procedure for most individuals over the age of 18 who are seeking a permanent way to improve or correct their vision. Some factors, such as general health and corneal thickness, may limit a person’s candidacy for PRK.
Therefore, it is important to speak with your ophthalmologist to determine if PRK is right for you.
Who should not get PRK?
PRK (PhotoRefractive Keratectomy) is a type of laser eye surgery used to correct vision and can be a good option for those who do not want the traditional flap created in the cornea during a LASIK procedure.
However, there are certain individuals who should not undergo PRK, including those who excessively participate in activities which may cause the eye to be bumped or jarred, due to the fact that the treated area is left exposed and vulnerable to injury as it heals.
Additionally, those with eyelid or corneal disease, athletes who play contact sports, and patients with severe vision impairments (e. g. keratoconus or scarring) may not be candidates for PRK surgery.
It is also not recommended for individuals who wish to dramatically change the size of their prescription lens and for those who have had a previous corneal transplant or have signs of glaucoma. Finally, pregnant or nursing women may not be suitable for PRK, as the effects of the medication used during the procedure can have unknown effects on a developing fetus or infant.
Is PRK worth the risk?
It depends on your individual situation and risk tolerance. PRK is not a riskier procedure than LASIK, but it does have certain risks that LASIK does not involve. For example, PRK is more likely than LASIK to cause dry eye symptoms and involves slower initial healing.
On the other hand, PRK is better for people with thinner corneas, who might not be able to safely have LASIK.
Before deciding whether PRK is worth the risk for you, it is important to discuss the potential risks and benefits with an eye doctor and make an educated decision based on your individual needs. It’s also important to consider whether LASIK is a better choice for you, depending on the thickness and shape of your corneas and the amount of correction you need.
Your eye doctor can help you compare the two procedures and determine which is the most appropriate for your particular eyes.
What is the success rate of PRK surgery?
The success rate of PRK surgery is approximately 95%. PRK (photorefractive keratectomy) is a forms of laser surgery used to correct nearsightedness, farsightedness, and astigmatism. While it is a less commonly performed laser surgery than LASIK, PRK has a number of advantages, including a low complication rate and minimal to no post-operative discomfort.
Most patients who undergo PRK surgery receive a significant improvement in their vision shortly after the procedure, typically within 24-48 hours. Over 80%-95% of patients who undergo PRK experience a 20/20 vision outcome or better, although some individuals may have fluctuations in their vision for several weeks after surgery.
While 20/20 vision is a common outcome for PRK patients, 20/40 vision or better (which is required for legal driving in the USA) has been reported in up to 99. 5% of PRK patients.
Generally, the most successful outcomes are seen when the patient has a substantial refractive error that is within the acceptable range for PRK surgery. PRK is also often used to correct mild astigmatism, although this condition can limit the success rate in some cases.
Ultimately, the success rate of PRK surgery depends largely on the skills of the ophthalmologist, so it is important to find an experienced and reputable surgeon to maximize your chances of a successful outcome.
Is PRK or LASIK better for astigmatism?
Both PRK and LASIK are viable options for correcting astigmatism. The main difference between the two surgeries is that PRK does not involve the use of a laser, while LASIK does. With PRK, the surface layer of the cornea is removed and reshaped in order to correct astigmatism.
With LASIK, a thin flap is created in order to access the inner layers of the cornea, which are then reshaped with a laser in order to correct astigmatism.
There are advantages and disadvantages to both PRK and LASIK that should be considered when determining which is the best option for astigmatism correction.
Advantages of PRK include the fact that it is associated with lower incidence of corneal nerve damage and less risk of corneal infection compared to LASIK. Additionally, PRK tends to have a short recovery period and can be used to treat even the most severe cases of astigmatism.
Advantages of LASIK include a shorter healing time, reduced risk of corneal infection, a more comfortable recovery, and the ability to treat mild to moderate astigmatism.
Ultimately, the best choice will depend on the severity of astigmatism, the anatomic characteristics of the eye, and the patient’s preferences. A patient should consult with an experienced and qualified surgeon to determine the best option for their individual situation.
How many years does PRK last?
PRK (photorefractive keratectomy) is a type of laser eye surgery that can be used to correct nearsightedness and astigmatism. The surgery reshapes the cornea with an excimer laser and generally lasts about 10 to 15 seconds per eye.
The effects of PRK can typically last around three years or more but may also need to be repeated in order to maintain the desired results. Generally, people who need PRK can expect to get the surgery at least once every 12 to 24 months.
However, the exact intervals between PRK often vary due to how much correction is needed and how the body is responding to the treatment.
The decision to have PRK repeated will be made by your ophthalmologist, who will take into consideration your corneal health, prescription, lifestyle and other factors in order to determine if a follow-up PRK should be done.
After a follow-up procedure, most people will not need another PRK procedure for at least another three years.
Which lasts longer LASIK or PRK?
The longevity of results for both LASIK and PRK depends on a variety of factors, but in general, studies have found that the refractive results of both procedures typically last for approximately 10-15 years.
Additionally, the stability of these refractive results may vary from patient to patient.
LASIK and PRK both employ laser technology to change the configuration of the cornea, thereby changing the focus of the eye. Both LASIK and PRK work to correct prescriptions for near- or far-sightedness and astigmatism.
However, the primary difference between the two is the method of cornea alteration. While the LASIK procedure involves the creation of a thin flap, to be lifted and then treated with the laser, PRK involves the complete removal of the epithelial layer of the cornea to treat the tissue with the laser.
Ultimately, laser vision correction procedures and the length of time that their effects last depend on the patient’s lifestyle and the initial interaction of the laser procedure with the patient’s eye.
Patients that have following proper pre- and post-operative instructions, received a thorough examination by the surgeon, and have refrained from activities such as smoking or excessive alcohol consumption prior to and after the procedure, may find that the refractive effects of their surgery last significantly longer than someone with unhealthy lifestyle habits.
Additionally, regular and timely follow-up visits with the ophthalmologist can promote long-term results.
Can PRK be done twice?
Yes, PRK (photorefractive keratectomy) can be done twice. PRK is a type of laser eye surgery that reshapes the cornea in order to correct refractive errors, such as nearsightedness, farsightedness, and astigmatism.
Depending on your individual refractive error, you may need more than one surgery to achieve optimal results.
However, if PRK is done more than once, it is important to keep in mind that there will likely be an extended recovery period and it is necessary to wait a few months between surgeries. Additionally, if you go back for a second PRK procedure, your doctor may need to use a lower power of exposure, as higher exposure can damage the corneal tissue.
In conclusion, if you need more than one PRK procedure, it is important to take into account the risks associated with multiple surgeries, such as reduced vision, increased risk of infection or scarring, or an extended recovery period.
It is always best to consult with your doctor before making a decision.
Does vision deteriorate after PRK?
Yes, vision can deteriorate after PRK (Photorefractive keratectomy) surgery, but this can vary depending on the individual. Generally speaking, there is a period of vision disturbances that occur in the immediate weeks and months following the procedure, including blurry or foggy vision, dry eyes, glare, and halos.
These vision irregularities may last for up to a year or longer, though eventually most people can expect to see improved vision.
Some people may still experience vision issues even after the initial adjustment period is over. Some possible factors that can contribute to a decline in vision after PRK include overcorrecting or undercorrecting the refractive error, issues with the healing process, and the development of additional corneal irregularities, such as scarring of the cornea.
It is also possible to develop astigmatism as a result of PRK surgery.
If you are considering PRK surgery, it is important to understand the possible risks involved and to speak to an experienced ophthalmologist or optometrist who can assess your individual eye health and determine the best type of treatment for you.
Is PRK safer long term?
Overall, PRK is considered to be a safe procedure and the long-term safety of the procedure has been studied extensively. Research indicates that PRK is a safe procedure for correcting vision with a low incidence of serious adverse effects.
Compared to other types of laser vision correction such as LASIK, PRK may offer a slightly lower risk of vision-related complications in later years. Studies have concluded that most patients who undergo PRK maintain stable, corrected vision for more than 15 years without needing additional treatments.
In addition to its long-term safety, PRK is also beneficial because it requires less medical intervention than other types of laser vision correction. With PRK, there is no risk of developing a corneal flap complication which can happen during LASIK or LASEK procedures.
PRK also has a shorter healing and recovery time in comparison to other procedures, meaning patients can return to their normal activities very quickly. As PRK is a relatively simple procedure, it is much less likely to cause long-term issues or problems.
Overall, PRK provides the potential for a highly successful long-term outcome in terms of safety and vision correction. While some patients may require additional treatments after a number of years, the procedure has been found to deliver long-term stability and predictability for most.
