Abstract
|
|
|
To evaluate the long-term result of photorefractive keratectomy (PPK) using masking fluid, retrospective review of 17 eyes with minimum follow-up time of 20 months was performed. All 17 eyes had uncorrected visual acuities of above 0.9 Mean
manifest
refraction was -4.18±1.04 (mean±standard deviation) diopters(D) at the preoperative, -0.04±0.30 D at one year and -0.21±0.22 D at the final visit (21.64±1.27 months) after operation. The change of mean keratometric power was 1.23±0.68 D,
and
mean
corrected rate (achieved/attempted correction) was 0.97±0.10. There were decentrations within 0.2mm in 3 eyes(18%) and no 'central island' in computerized videokeratography. Five eyes (29%) with increased intraocular pressure of above 20mmHg
were
well
controlled a beta-blocker and/or cessation of corticosteroid therapy. The corneal opacity was found in one eye(6%).
Our reports including the previous suggest that PRK using masking fluid(hydration technique) showed small amount of refractive regression and complication.
