PRK Laser Eye Surgery vs. LASIK: Pros Cons - RealSelf PRK technically leaves your anatomy more “intact” than LASIK does Dr Lee Katzman , an ophthalmologist in San Diego, says PRK is also a better choice for someone with a job that involves regular physical contact with the face or eye area because there’s no risk of the corneal cap becoming dislodged, like there is with a LASIK flap
Is PRK Possible for People Who Have Astigmatism? - RealSelf The laser that is used to treat your nearsightedness or farsightedness is the same laser that treats your astigmatism, whether you have PRK or LASIK There are maximum amounts of nearsightedness, farsightedness, and astigmatism that the FDA has approved these laser for, but assuming you fall within the range, you should have no problem have
PRK Laser Eye Surgery Reviews | Was it Worth It? - RealSelf After reading recent reviews of PRK surgery, it appears that several of the patients who undertook the process possibly should not have been advised to undertake corrective eye surgery From my understanding, surgery should proceed where vision is significantly impacted (eg -4 or worse) and
Floaters in Eyes After PRK, Why is This? - RealSelf Before my PRK surgery, I would occasionally notice floaters, but the difference now is that I notice them all the time I read that PRK can not cause floaters since the surgery does not affect the vitreous humor, but that it is possible that PRK could cause one to notice their pre-existing floaters more Why is this?
What is PRK? Is It Painful? - RealSelf Think of PRK as 'Flap-less LASIK' Both procedures are identical when it comes to correcting your eyeglass prescription, the only difference is that with LASIK a corneal flap is cut first (with a different machine) and in PRK the surface corneal epithelial cells (thin outer covering of the cornea) are removed first
What is the Recovery Timeline After the PRK Procedure? - RealSelf Recovery after PRK occurs in stages:Stage 1 - seconds to minutes after the procedure, the vision is surprisingly clear, actually better than it is after LASIK at this point Stage 2 - begins about 30-60 min after the procedure, as the numbing drops used during surgery wear off The patient begins to experience mild to moderate discomfort in the eye
Is It Common for Your Vision to Be Worse After a PRK . . . - RealSelf There is no question that PRK, whether it is an initial procedure or enhancement, has a slower recovery The reason for this is that the corneal surface has more healing to do after PRK The initial phase of healing with PRK takes about 5-10 days and varies depending on the healing speed of the individual
I have a central corneal thickness of 470 in both eyes, (too . . . - RealSelf Your case falls in the grey zone for PRK procedure Even though the residual cornea after your treatment would be above 250 Micron (the lowest number which is considered to be a safe and within the standard of care), some physicians consider any cornea less than 500 micron at a higher risk for destabilization following any type of corneal thining procedure and advise against them
Thin Corneas, High Prescription. . . . PRK? - RealSelf PRK removes about 14 microns (amount of corneal tissue) per diopter (-1 00 prescription) of treatment for a standard 8 5 mm ablation zone with a normal blend This would leave you with about 375 microns of residual bed (amount of corneal tissue thickness)
Unsatisfactory PRK Results - What went wrong? Does this mean . . . - RealSelf PRK is an excellent method of correcting nearsightedness, but its biggest drawback is that it takes longer to heal Unlike LASIK where most people have good vision the next day, with PRK there is usually substantial fluctuation of vision for the first several weeks and it can take as much as three or four months before the final result is known
