【Abstract】 Objective To evaluate the effectiveness and safety of LASIK in treanting hyperopia.Methods 30 eyes of 16 patients with hyperopia from +3.05D to +12.50D were treated with LASIK,the mean preoperative spherical equivalent was +7.09D±2.62D.All of the cases were followed up for 12 months.Results There was no serious complication during the operation.At one year postoperatively,the number of eyes of residual refraction in +1.00D and +2.00D were 12 eyes(40%) and 19 eyes(63.3%).100% and 80% eyes got uncorrected near visual≥0.5 and ≥1.0,respectively,86.7% and 30% eyes got uncorrected far vision ≥0.5 and ≥1.0 respectively.One eye (3.3%) lost 1 line of best corrected visual acuity and five eyes (16.7%) had halos.Conclusion It is demonstrated the LASIK is a safe and effective technique for the treatment of hyperopia.Some modification of the algorithm and laser nomogram is helpful to improve the predictability and stability of the surgery.更多还原
