AbstractThis study evaluated the accuracy of total keratometry (TK) and standard keratometry (K) for intraocular lens (IOL) power calculation in eyes treated with femtosecond laser-assisted cataract surgery. The retrospective study included a retrospective analysis of data from 62 patients (91 eyes) who underwent uneventful femtosecond laser-assisted cataract surgery with Artis PL E (Cristalens Industrie, Lannion, France) IOL implantation by a single surgeon between May 2020 and December 2020 in Severance Hospital, Seoul, South Korea. The new IOLMaster 700 biometry device (Carl Zeiss Meditec, Jena, Germany) was used to calculate TK and K. The mean absolute error (MAE), median absolute error (MedAE), and the percentages of eyes within prediction errors of ± 0.25 D, ± 0.50 D, and ± 1.00 D were calculated for all IOL formulas (SRK/T, Hoffer-Q, Haigis, Holladay 1, Holladay 2, and Barrett Universal II). There was strong agreement between K and TK (intraclass correlation coefficient = 0.99), with a mean difference of 0.04 D. For all formulas, MAE tended to be lower for TK than for K, and relatively lower MAE and MedAE values were observed for SRK/T and Holladay 1. Furthermore, for all formulas, a greater proportion of eyes fell within ± 0.25 D of the predicted postoperative spherical equivalent range in the TK group than in the K group. However, differences in MAEs, MedAEs, and percentages of eyes within the above prediction errors were not statistically significant. In conclusion, TK and K exhibit comparable performance for refractive prediction in eyes undergoing femtosecond laser-assisted cataract surgery.

ABSTRACT Objective To report opacification of hydrophilic acrylic and silicone foldable intraocular lenses (IOL). Designs Case series. Participants Five patients with IOL opacification. Results We report five eyes of five patients with late opacification of the intraocular lens (IOL). Three patients had hydrophilic acrylic (SC60B-OUV-MDR, Inc), two had silicone IOL (Allergan SI30NB). Two out of the three patients with opacified hydrophilic acrylic IOLs had diabetes mellitus. Three eyes with opacified acrylic IOL underwent IOL exchange with hydrophobic acrylic IOL. Two silicone IOL patients had no visually significant opacification and were managed conservatively. Conclusion IOL optic opacification in hydrophilic acrylic and silicone IOL may be due to defective material, manufacturing process, storage.

AimTo describe the long-term outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) with an anterior chamber intraocular lens (ACIOL) compared to secondary posterior chamber (PC) IOL.MethodsThis was a retrospective comparative cohort study. The clinical data of 82 eyes from 82 consecutive patients with pseudophakic (PBK) or aphakic bullous keratopathy (ABK) who either underwent DSAEK with retained or secondary ACIOL (n=23) or DSAEK with IOL exchange and/or secondary PCIOL (retropupillary iris-claw IOL, n=25; intrascleral-fixated IOL, n=29; or sulcus IOL, n=5) were analysed. The main outcome measures were graft survival and complications up to 5 years.ResultsThe graft survival in the secondary PCIOL group was superior than the ACIOL group over 5 years (year 1, 100.0% vs 100.0%; year 3, 94.7% vs 75.0%; year 5, 91.1% vs 60.6%, p=0.022). The presence of an ACIOL was a significant risk factor associated with graft failure (HR, 4.801; 95% CI, 1.406 to 16.396, p=0.012) compared to a secondary PCIOL. There was no significant difference in the rate of graft detachment and elevated intraocular pressure between the groups. There were five cases (9.3%) of IOL subluxation or dislocation in the retropupillary iris-claw and intrascleral-fixated IOL groups.ConclusionsEyes that underwent DSAEK with ACIOL in situ had poorer long-term graft survival compared with those with secondary PCIOL. Intraocular lens exchange was not associated with a higher complication rate. In ABK or PBK eyes with ACIOL, we recommend performing IOL exchange and/or secondary PCIOL implantation combined with endothelial keratoplasty.

Three pseudophakic patients presented with recurrent, unilateral vitreous hemorrhage, one of which also had uveitis, glaucoma, and hyphema, consistent with “uveitis–glaucoma–hyphema (UGH)-Plus” syndrome. Arcuate transillumination defects secondary to inadvertent placement of 1 intraocular lens (IOL) haptic in the sulcus were identified in each case. The second haptic and optic were located in the capsular bag. The IOLs were all single-piece foldable acrylic lenses with square-edge haptic design. Surgical repositioning of the malpositioned haptic from the sulcus to the retrocapsular space resulted in the resolution of the recurrent vitreous hemorrhage. This series highlights the fact that recurrent vitreous hemorrhage secondary to iris chafing, with or without UGH, may occur in cases where a square-edge IOL haptic is placed in the sulcus. Vitrectomy with repositioning of the malpositioned IOL is a simple alternative to IOL exchange in these cases.
