Question 1

convergence insufficiency after prk?

Accepted Answer

Latent muscle proble: This sounds like something present but hidden prior to the surgery. I have never heard of refractory surgeries causing muscle imbalances.

Question 2

how long does it take for vision to clear after prk surgery?

Accepted Answer

1-2 weeks: Prk surgery is accompanied by swelling of the front of the eye (cornea) which usually lasts one week and the vision comes in rapidly in the next week (in an uncomplicated case).  If yours is taking longer, then check in with the surgeon who did the prk for treatment.

Question 3

what percentage of people eventually see 20/20 uncorrected after having prk?

Accepted Answer

Very high percentage: The results depend on the starting point. Lower corrections get  somewhat  better results faster than higher corrections. In general, 90-98% of eyes will see 20/25 or 20/20 or better without correction after PRK surgery.

Question 4

should i choose prk or lasik surgery?

Accepted Answer

Depends : Depends on clinical characteristics of your eyes and your preferences, the laser treatment preferred can vary.  See your corneal surgeon.

Question 5

what are advantages of refractive surgery prk?

Accepted Answer

No flap: The advantages of prk over lasik are that it can be performed on thinner corneas as there is no flap to be cut. This also removes some possible complications. The down side is longer visual recovery and some post-operative pain. Consult a refractive specialist in order to see which procedure is best for you.

Question 6

what is involved in a photorefractive keratectomy (prk)?

Accepted Answer

PRK: First it is determined if you are a good candidate for the procedure.  Prk is done with eye drop anesthesia.  You recline in a chair similar to a dentist chair, and an instrument is placed to hold the eyelids open.  You look upward toward the laser opening.  The surgeon checks the positioning, settings, and alignment, and proceeds with treatment.  A bandage contact lens may be placed for comfort.

Question 7

what makes you a candidate for prk (photorefractive keratectomy)?

Accepted Answer

Many criteria: There are many criteria that establish candidacy for any refractive surgery. The prescription, the corneal thickness and curvature and the overall health of the eye are some of these. A consultation with an experienced surgeon is the best way to determine whether you are a candidate for vision correction surgery and which procedure is best for you.

Question 8

am i eligibile for prk when i had corneal scar?

Accepted Answer

It is possible: Depending on the depth, size and location of the scar, prk or even lasik may be possible vision correction options for you. Your best bet would be an evaluation with a lasik doctor to determine your candiddacy for the treatment.

Question 9

how would   prepare for prk?

Accepted Answer

See ophthalmologist: You lasik/prk surgeon will do all the work for you in your pre-treatment examinations and answer all questions you might have.  On the day of surgery, eat lightly and try not to worry.  If you are a terribly nervous sort, you might need to have a valium prescribed which your lasik surgeon can prescribe.

Question 10

Accepted Answer

Photorefractive: Keratectomy. Type of laser eye surgery. It preceded lasik surgery and is said to have davantages & disadvantages to lasik surgery. This should be discussed with an experienced eye surgeon try and find a surgeon who does at least 5 - 10 such procedures/week. Good luck.
