PurposeWe evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery.MethodsPentacam examination was performed in 88 eyes from 88 patients to evaluate central anterior chamber depth (ACDpentacam), nuclear density (Densitometrypentacam), anterior chamber volume (ACV), and lens thickness (LTpentacam). We compared values of ACDpentacam with those of ultrasound (ACDsono) and also compared Densitometrypentacam values with those of Lens Opacities Classification System (LOCS III) classification. We evaluated the effect of the following preoperative values measured with Pentacam on postoperative endothelial cell loss: pupil size measured both preoperatively and before capsulorrhexsis (PupilCCC), amount of viscoelastics, and LT measured by ultrasound (LTsono).ResultsA significant concordance was found between the two grading methods of nuclear opacity: Densitometrypentacam and LOCS III classification (τb = 0.414, p = 0.000). We also found a positive correlation between ACDpentacam and ACDsono (r = 0.823, p = 0.000) and between ACDpentacam and ACV (r = 0.650, p = 0.000). There were significant differences between the results of LTpentacam and LTsono. The final regression model identified Densitometrypentacam, viscoelastics and PupilCCC as independent predictors of decreased postoperative corneal endothelial cell density (CD) at postoperative day 3, and Densitometrypentacam, viscoelastics, and ACV as independent predictors of decreased CD two months postoperatively (p<0.05).ConclusionsGood agreement was found between all results obtained with the Pentacam and conventional methods except LT. Analyzing anterior chamber parameters preoperatively using Pentacam could be helpful to predict postoperative endothelial cell loss.

Purpose: To evaluate the stability of implantable collamer lens (ICL, Staar Surgical AG, Niau, Switzerland) by comparing changes of tilt, decentration and anteroir chamber depth after ICL implantation during 1 year. Methods: The results of 8 high myopic patients (16 eyes) that had received ICL implantation were retrospectively studied. Tilt and decentration of ICL were measured using an anterior eye segment analysis system (Scheimpflug camera, EAS-1000, Nidek, Japan). Anterior chamber depth was measured in both eyes preoperatively and postoperatively by Scheimpflug camera. The follow-up period was 1 year. Results: Tilt was 1.90 ± 1.23°, 1.75 ± 0.80°, 1.64 ± 0.86°, 2.08 ± 1.33° (p = 0.36) and decentration were 0.04 ± 0.01 mm, 0.03 ± 0.01 mm, 0.03 ± 0.02 mm, 0.04 ± 0.02 mm (p = 0.59) at 1 week, 1 month, 6 months and 1 year respectively. Tilt and decentration showed no significant change after ICL implantation. The average anterior chamber depth was 2.85 ± 0.26 mm preoperatively, and 2.17 ± 0.39 mm, 2.06 ± 0.31 mm, 2.06 ± 0.34 mm, 2.04 ± 0.35 mm at 1 week, 1 month, 6 months and 1 year respectively. Anterior chamber depth became narrow after ICL implantation (p = 0.02), but showed no significant narrowing postoperatively (p = 0.08). Conclusions: The IOL position remained stable, with no significant changes for an extended period of tilt, decentration, or anterior chamber depth after ICL implantation.
