Purpose: To evaluate the efficacy and safety of multifocal cornea by excimer laser as a treatment of presbyopia. Method: There were 2 groups. Group 1 includes 36 eyes of 20 hyperopia patients and group 2 includes 36 eyes of 18 myopic patients. Preoperative spherical equivalent was +0.85 +/- 0.51 in group 1 and –4.82 +/- 2.49in group 2. Cetral corneal was used for far vision and peripheral corneal was for the near vision. Distance visual acuity, best corrected visual acuity, uncorrected and distance corrected nealr visual acuity were measured. Results: 88% and 77% of eyes were within 0.5 D in group 1 and 2 respec…
