Residual Refractive Effect of Presbyopic LASIK Omnifocal Corneal Ablation With a Monofocal Spherical IOL: Case Report
Narrative Responses:
Purpose
The purpose of this case report is to analyze the residual refractive effect of Presbylasik Omnifocal Corneal Ablation with a monofocal spherical IOL in two eyes of one patient undergoing cataract surgery with near/distance vision demands.
Methods
Case series. Two eyes with prior Presbylasik Omnifocal Corneal Ablation (36 months follow-up) were included in the study. The preoperative evaluation included distance and near UCVA, BSCVA, manifest refraction, corneal topography using TOMEY TM5, and LENSTAR. Cataract surgery was performed by the same surgeon in the two eyes using Alcon Infinity, with IOL SN60AT Monofocal Spherical lens implantation. Both Haigis L and Clinical History formulas were used in lens calculation. The postop evaluation included distance and near UCVA, BSCVA, and manifest refraction .
Results
The preoperative distance UCVA was 20/50, near UCVA Jaeger III in the both eyes. Distance BSCVA 20/40 for the right eye and 20/30 for the left eye with a mean sphere of +0,88D, mean cylinder + 0,69D. Postoperative data with 18 months follow up showed distance/near UCVA 20/25 J III OD and 20/40 JI OS, Near BSCVA JI OD and distance BSCVA 20/25 OS with mean shpere -0,25D and mena cylinder -0,25D. No loss of BSCVA lines were recorded
Conclusion
Although more patients are needed, the residual refractive effect of Presbylasik Omnifocal Corneal Ablation with a spherical monofocal IOL shows predictible results for near/distance visual acuity. This, in our opinion, allows us to avoid the use of a multifocal aspherical IOL with a difficult lens calculation.
