Abstract:
AlM:To investigate the factors and solutions of Tibetan Plateau excimer laser in situ keratomileusis ( LASlK ) for myopia overcorrection.METHODS: The relevant information, 32 cases ( 58 eyes) in 126 cases (252 eyes) had obvious overcorrection after LASlK were analyzed.RESULTS: Two months after surgery, 32 cases ( 58 eyes) overcorrection (23. 0%), uncorrected visual acuity of 0. 5 ~0. 8, overcorrection range of +1. 50 ~ +2. 25DS, subjective inserts were ≥ 1. 0; Five case ( 7 eyes ) overcorrection 6mo after surgery (2. 8%), uncorrected visual acuity 0. 8~1. 0-2 , overcorrection range is +0. 75 ~+1. 25DS, subjective inserts were≥1. 0. Corneal thickness of overcorrection was 500~563μm, preoperative refraction was -5. 00 ~ -7. 50D, astigmatism -1. 50 ~ -2. 75DC, preoperative best corrected visual acuity ≥1. 0.CONCLUSlON: Overcorrection and long recovery time after LASlK in Tibet, possibly with local factors altitude, temperature, humidity, surgical parameters and situation.
