Binocular Visual Outcomes Of Laser Blended Vision For Presbyopia In Hyperopes

          Retrospective study of binocular visual outcomes of Laser Blended Vision (LBV) on Hyperopes with presbyopia using non-linear aspheric ablation profile and micro-monovision with Presbyond® program by Carl Zeiss Meditec®(Jena,Germany)

Centre Ocular Quirurgic de Terrassa, Terrassa,Barcelona,Spain. Private practice

LBV is a LASIK procedure combining micro-monovision in the near-preferred eye and emmetropia for the distance-prefered eye with extended depth of field achieved by aspheric laser ablation profile in both eyes.We present the bilateral visual outcomes obtained in 118 Hyperopes,mean age 58 years(range 45/76), 52 % female, minimum follow -up of 6 months, mean preoperative spherical equivalent (SEQ) +2.19,  (range) +1.01 to +5.38, enhancement rates and cross-blurr tolerance. We excluded any reason that contraindicates LASIK surgery and those patients with low stereopsis and no clear dominance. We use Excimer Laser Zeiss Mel-90 with Presbyond® program by Carl Zeiss Meditec®(Jena,Germany)

Six months after surgery and after enhancement procedures if required Mean Binocular Uncorrected Distance Visual Acuity (BUDVA) was 1.15 decimal (range: 0.7 to 1.5) Mean Uncorrected Binocular Intermediate Visual Acuity (BUIVA) was 0.9 (range: 0.5 to 1.5).Mean Binocular Uncorrected  Near Visual Acuity (BUNVA) was 1.11(range: 0.4 to 1.2).Enhancement rates: 37eyes of 236: 15.68%,21 of them on no dominant eye. No patients with permanent cross-blurr. SEQ of dominant eyes: mean 0 diopters (range:+0.5 to -0.5) SD : 0.28.SEQ of non-dominat eyes: mean -1.27D (range +0.38 to -2.5).

The LBV protocol provides an effective and safe mean to treat presbyopia in hyperopic patients with high  adaptation rates and good binocular performance.
