Abstract

PURPOSE
To evaluate clinical effects of laser thermal keratoplasty (LTK), LTK was performed in patients with presbyopia or hyperopia. METHODS: LTK was performed in 38 patients who was older than 45 between May and December 2001. Preoperative contact lens fitting and wearing for patients to experience the monovision was tried in all patients for one week. With LTK, we intended patients used dominant eyes for distance vision and nondominant eyes for near vision. Patients' satisfaction, refractive change and near visual acuity were evaluated for least 3 months after surgery. RESULTS: The mean improvement of near vision was 5.16 lines by test with Korean near vision chart. 79% (30 of 38) of patients were satisfied with the results of LTK. CONCLUSIONS: Monovision with LTK is thought to be a good option in patients with presbyopia.
