Abstract

Abstract Background To describe and analyze the real-life refractive, functional and safety outcomes of the Clareon® intraocular lens (IOL) after 3 years. Methods Data was collected retrospectively for observational purposes between July 2017 and December 2019 in the ophthalmology department of Desgenettes military hospital in Lyon, France. Eyes that underwent cataract surgery with Claeron® implantation were consecutively included. Patients with a systemic or ocular condition that could affect the visual outcome were excluded. Postoperative corrected (CDVA) and uncorrected (UDVA) distance visual acuities as well as capsule and IOL transparency were assessed at 1 month and 3 years. Results A total of 326 eyes were analyzed at one month and 191 eyes were reassessed at the 3-year follow-up visit. At 3 years, the mean CDVA was 0.003 LogMAR (95% confidence interval [CI]: -0.003 to -0.01) and the mean UDVA was 0.075 (95% CI: 0.054 to 0.095). Three quarters of the patients had an UDVA ≥ 0.097 logMAR (20/25 Snellen equivalent) and 50% had an UDVA ≥ 0 (20/20). The absence of glistening was reported in 95.3% of cases and 4.7% [9] of patients experienced a clinically significant posterior capsular opacification (PCO) for which Nd:YAG treatment was required. Conclusions This real-life study reports high-performance and stable long-term refractive outcomes of the Clareon® IOL with good safety in terms of PCO and glistening.

Abstract

The aim of this study was to compare the visual and refractive outcomes of total keratometry (TK) versus anterior keratometry (AK) measurements of the IOLMaster 700® (Carl Zeiss Meditec AG, Jena, Germany) in surgery for age-related cataract with preexisting corneal astigmatism. Monocentric retrospective comparative study. The IOLMaster 700® biometer was used in the 2 groups: in AK mode (AK group) and in TK mode (TK group), for toric IOL (AT TORBI 709 MP) calculation with ZCALC®, Zeiss toric IOL calculator. A 2:1 matching was made between the AK and TK groups. Uncorrected distance visual acuity (UDVA), the correction index and the error in predicted residual astigmatism were analyzed 1 month postoperatively using the vector analysis by the Alpins method. The whole cohort included 405 eyes distributed as follows after 2:1 matching: 158 eyes in the AK group and 79 eyes in the TK group. The mean UDVA was similar in both groups (0.07 ± 0.10 LogMAR; p = 0.587). No significant difference in mean absolute error in predicted residual astigmatism (0.37 ± 0.33 D versus 0.35 ± 0.26 D; p = 0.545) and in mean centroid error in predicted residual astigmatism (0.19 ± 0.49 at 3° and 0.06 ± 0.46 at 0°; p = 0.008 and 0.161 respectively for the x- and y-components) was found between the AK and TK groups. TK of the IOLMaster 700® gives excellent refractive and visual outcomes, comparable to those obtained in AK mode, without showing its superiority for corneas with regular astigmatism.

Abstract

PURPOSE To assess the impact of intravitreal injections (IVTI) on ocular surface of patients treated with multiple injections. METHODS Prospective, tricentric study conducted in patients treated with unilateral IVTI. An asepsis protocol with povidone-iodine was used for all patients during IVTI. The primary endpoint was the difference between the pre-IVTI Ocular Surface Disease Index (OSDI 1) score and that measured on day one (D1) post-IVTI (OSDI 2). Secondary endpoints were the evaluation of predictive factors for OSDI scores, pain assessment on D1, and the Lacrydiag® analysis of tears from the injected eye versus contralateral eye before IVTI. RESULTS Two hundred and nineteen patients with a mean age of 75.9 ± 10 years were included. The mean OSDI2-OSDI1 difference was 19.2 ± 20.6 (p
