Central PresbyLASIK for Hyperopia and Presbyopia Using Micro-monovision With the Technolas 217P Platform and SUPRACOR Algorithm.

Purpose: To analyze the refractive outcomes and satisfaction of presbyopic hyperopes treated with central presbyopicLASIK (presbyLASIK) with induced micro-monovision.

Methods: This retrospective study included 74 eyes of 37 patients treated with central presbyLASIK with micro-monovision using the Technolas 217P excimer laser (Technolas Perfect Vision GmbH, Munich, Germany) between June 2011 and March 2014. Study parameters included uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA), aberrometry, the central steep zone, and patient satisfaction.

Results: Median age was 54.3±4 years (range: 46 to 63 years). Mean postoperative spherical equivalent refraction was 0.00±0.58 diopters (D) for dominant eyes and -0.51±0.54 D for non-dominant eyes. Mean binocular UDVA was 0.01±0.10 logMAR (Snellen 20/20) at 6 months and -0.01±0.05 logMAR (Snellen 20/19) at 1 year postoperatively. Mean binocular UNVA was 0.18±0.14 logMAR (Parinaud 2) (Jaeger 1) at 6 months and 0.18±0.12 logMAR (Parinaud 2) (Jaeger 1) at 1 year postoperatively. At 6 months, 79.31% of patients achieved 20/25 and could read Parinaud 2 (Jaeger 1) binocularly. At 1 year, 84.21% of patients achieved 20/25 and could read Parinaud 2 (Jaeger 1) binocularly. The mean central steep zone was 2.35±1.00 D. There were significantly more negative spherical aberration and vertical coma in the central 5 mm postoperatively (P<.05). The re-treatment rate was 6.75%. Eighty-three percent of these patients did not need any glasses for distance and near vision.

Conclusions: This procedure may improve functional near, intermediate, and distance vision in presbyopic patients with low and moderate hyperopia.
