Possible complications PRK

  A few complications PRK includes:

•Long a healing continuance

•Pain

•Glare, halos, or starburst Aberrations

•Under-or supercorrecting

•Recurrence myopias

•Increased an ophthalmotonus

Turbidity •Corneal

•Scarring

•Reduced is better corrected visual acuteness

Acuteness •Reduced in low light

  PRK can be executed on one eye for once to estimate effects of procedure and to guarantee adequate vision during healing process. (The note: Guidance on sanitary inspection behind foodstuff and medicines recommends a 3-month's continuance before second surgery PRK). The activity, demanding good binocular vision, possibly, it is necessary to suspend between surgeries and during time, sometimes to extend, curing continuances.

  Some patients Post-PRK complained of bright light, halos, and starburst aberrations which can be effect of postoperative corneal turbidity which can develop in time of process of healing. Using the up-to-date lasers for a year 2005, it is rather rare after 6 months, but under reports, symptoms were casually impeded more longly than year in some cases.

  Predictability of coming to an end refracting correcting after healing is not completely exact, especially for those with more serious short-sightedness. It can lead under/over-correction a refracting error. In case of supercorrecting premature presbyopia - possibility.

  In 1 - 3 % of cases losses of the best corrected visual acuteness (BCVA) can end, because of decentered abljatsionnyh bands or other surgical complications. (The note: Losses BCVA under reports 5 to 15x it is more probable with PRK than that following of use of expanded contacts of deterioration). Effects PRK in refined BCVA about twice so it is frequent, as it causes losses. Center shift becomes ever less a problem with more up-to-date lasers, using the difficult focusing eye and tracking methods.
