Purpose To report the visual acuity outcomes, predictability, and safety of the Zeiss VisuMax-MEL80 platform for the treatment of myopia.

Methods Retrospective review of initial series of 46 eyes of 26 patients treated for myopia using the Zeiss Visumax-MEL80 platform All eyes had a treatment goal of emmetropia. All data was analyzed using JMP (SAS, Cary, NC) and SPSS (SPSS Inc, Chicago, Illinois) All Snellen visual acuities were converted to a logMAR scale based on a logMAR conversion table Individual letter adjustments where accounted for as 0.02 logMAR per letter. A Snellen acuity was rounded down one Snellen line if the logMAR score was >0.04 for that respective line. LogMAR scores were converted back to Snellen fractions for the purposes of categorizing the results

Patient Characteristics Demographics Patient Characteristics Characteristic All Patients (N=46) Age mean (SD) 33.13 (8.97) Female N (%) 25 (54.3) Preoperative UCVA mean (range) 1.11 logMAR (0.21 – 1.34) Preoperative MRSE mean (range) -3.97 D (-0.875- -6.75) Time to post-operative month one visit 43.8 days( 28 – 90)

Preoperative MRSE & UCVA -3.97 (SD: 1.67; Range: -0.875 - -6.75). 1.11 logMAR (SD: 0.29; Range: 0.21 – 1.34)

Post-operative Day 1 and Month 1 POD 1 UCVA 73.9% of eyes had UCVA of 20/20 or better 91.3% of eyes had UCVA of 20/25 or better POM 1 UCVA -0.029 logMAR (SD: 0.09, Range: -0.18 – 0.28) 87.0% had UCVA of 20/20 or better 97.9% of eyes had UCVA of 20/25 or better POM 1 BCVA -0.0726 (SD: 0.078; Range: -0.3 – 0.04) 100% of eyes had BCVA of 20/20 or better

Pre-op and Post-op UCVA

POM 1 MRSE 89.1% of eyes were within +/- 0.50 D of emmetropia

POM 1 Attempted vs. Achieved SE r2 = 0.945

Conclusion Our results show that LASIK using the VisuMax- MEL80 platform is effective, predictable, and safe in the treatment of myopia. References Holladay JT. Visual acuity measurements.
