PURPOSE
We estimated the incidence of retinal lesions at preoperative evaluation of retina for LASIK and investigate its clinical importance. METHODS: We estimated retrospectively the incidence of retinal lesions of the patients who visited our hospital with the purpose of correction of refractive error. The examination of retina upto periphery was done preoperatively. RESULTS: The mean spherical value and axial length were -6.5 +/- 3.4 diopters (range -26.0 ~ +17.0) and 25.4 +/- 2.0mm (range 15.7 ~ 34.5), respectively. The retinal lesions were found in 189 eyes of 139 persons (12.4%). Among them degenerative changes were found in 48 eyes of 34 persons, chorioretinal scars in 7 eyes of 7 persons, pigmented lesions in 28 eyes of 24 persons, and miscellaneous lesions in 106 eyes of 74 persons. There was a significant increase of spherical value and axial length in the group with retinal lesions -7.9 +/- 4.5 diopters (range -26.00 ~ -2.25), 26.5 +/- 2.3mm (range 23.1 ~ 34.5) compared to that without retinal lesions -6.1 +/- 3.4 diopters (range -25.00 ~ 17.00), 25.4 +/- 2.1mm (range 15.7 ~ 35.4). And the incidence of degenerative change and retinal tear was significantly increased in moderate myopes more than -4 diopters. CONCLUSIONS: LASIK is relatively a kind of safe refractive surgery, but to prevent the unexpected postoperative retinal complications, it is essential to thoroughly examine the retina upto periphery before surgery. |
