Purpose
To investigate the visual and refractive outcomes of patients implanted with a rotationally asymmetric refractive multifocal IOL (Lentis Mplus, Teleon) after cataract surgery in patients with previous myopic corneal laser refractive surgery.
Setting
Vissum (Grupo Miranza), Alicante, Spain
Methods
A retrospective analysis was carried out at a single center, analyzing 21 eyes (14 patients) that had received previous laser corneal myopic refractive surgery and were subsequently implanted with the LENTIS Mplus +1.5 multifocal IOL due to cataract surgery (from January 2015 to October 2023). A comprehensive ophthalmologic exam was done before and after surgery at 1, 3, and 6 months. Visual and refractive outcomes for both far and near distances were registered. The Wilcoxon signed rank test or student's t test will determine statistical significance of pre and post treatment differences, depending on the sample's normal distribution. All hypothesis tests will use 0.05 significance.
Results
Mean age was 64,9 years. There were significant differences for uncorrected visual acuity (VA) for far, mean preop was 0,77 (logMAR) and mean postop was 0,10 (p<0.05). Mean spherical equivalent (SE) preop was -1,66D and postop 0,58D (p<0.05). Mean corrected VA for far was 0,39 preop and 0,02 postop (p<0.05). Mean corrected VA for near preop was 0,12 and 0,06 postop (p<0,05), whereas uncorrected VA for near did not exhibit significant difference, mean preop was 0,22 and postop was 0,28 (p>0,05). We did not observe significant differences for corneal spherical aberration, coma, or higher order aberration (HOA) (p>0,05). The mean postoperative coma was 0,21, spherical aberration 0,10 and HOA 0,31µ. The enhancement rate was 19% (4 eyes).
Conclusions
After cataract surgery, the LENTIS Mplus +1.5 multifocal intraocular lens (IOL) was able to successfully improve the visual and refractive results at far and near distance in patients who had previously undergone myopic corneal laser refractive surgery. Compared to preop, it should be noted that UNVA remained unchanged in good levels of 0.2 logMAR (cataract induced preoperative SE of -1.6D) thanks to the refractive correction (+1.5D) of the IOL for near, avoiding the deterioration of the unaided near visual function usually observed after cataract surgery when monofocal IOLs are implanted.
