Purpose
The Lentis Comfort® LS-313 MF15 intraocular lens (IOL) is an EDOF, refractive segmented and asymmetrical IOL with an aspheric surface with a posterior sector-shaped, near-vision segment, providing 1.5 D of near addition (add) at the IOL plane. The aim of our study is to analyze the functional and refractive postoperative outcomes at 1 month under real-life conditions.
Setting
This retrospective study included patients who underwent cataract surgery with implantation of LS-313 MF15 (group 1) and its toric version LS-313 MF15T (group 2), by a team of 5 surgeons at Desgenettes military hospital in Lyon, between July 2020 and May 2023.
Methods
Patients were consecutively implanted, Toric IOL was chosen in case of TK astigmatism superior or equal to 0,75D based on IOL Master 700™.
All patients were reassessed one month after surgery. Outcome evaluation criteria included uncorrected distance (UDVA) and near visual acuity (UNVA), subjective spherical equivalent (SE) and minimum addition to read Parinaud 2. All visual acuity tests were conducted monocularly.
Exclusion criteria included all pathologies likely to cause a decreased visual acuity not related to cataract.
Results
Three hundred and sixteen eyes were implanted, including 245 conventional lens and 71 Toric lens. Mean age and axial length were comparable between the 2 groups.
Concerning the total cohort (n=316 eyes), mean UDVA was 0.006 logMAR (±0.09), UNVA was 0.327 logMAR (±0.17) at 40 cm.
The combined criterion "UCVA ≤ 0,1 logMar and ≤ P3" was achieved in 52% of eyes. The mean post-operative SE was -0.06 D (±0.26) and the mean
addition required to read P2 was + 1.48 D (±0.63). The comparison between the 2 groups showed any statistical difference for all the functional criteria evaluated: (group 1 vs group 2) UDVA (0.004±0.10 vs 0.02±0.07, p= 0.063) UNVA (0.34±0.18 vs 0.30±0.17, p=0.292).
No safety signals were observed during this study.
Conclusions
This comparative study provides the first real-life assessment of the refractive performance of the Lentis Comfort® LS-313 MF15 vs its toric version.
We reported that this EDOF IOL does not penalize distance vision, while providing very appreciable near vision comfort (P3 monocular). The toric correction performed too similarly whatever the orientation of the TOR, confirming that surprisingly the near part of the optic does not necessarily have to be placed inferiorly during surgery.
Among the very heterogeneous choice of EDOF IOLs, this Lentis Confort® lens offers refractive quality with depth of field without penalizing distance vision. Results with toric IOL are comparable to that of standard optics.
