CONCLUSIONS: The USE-HF and USE-LF has comparable accuracy in Vg measurements while USE-HF had an advantage regarding better spatial resolution. The change trend of Vg was in accord with the growth phase of New Zealand white rabbits, which usually results in sexual maturity at 5 months old. This implies that Vg can be used as a biomarker parameter for evaluating the mechanical properties of the lens undergoing physiological changes. PMID: 31077713 [PubMed - as supplied by publisher]
CONCLUSIONS: A structured biometry training course may improve the accuracy of preoperative IOL calculations to achieve the postoperative refractive target. Ophthalmology training programs should include structured biometry teaching in their curricula.
Use of higher frequency ultrasound for phacoemulsification of moderate to hard cataracts leads to lower effective phaco time and estimated fluid loss as well as a better preserved endothelium upto one year
Conclusion: Intraoperative and postoperative parameters after torsional phacoemulsification are comparable in diabetics and nondiabetics. Endothelial changes and pachymetry may be related to the grade of cataract in diabetics.
Conclusion: SO-filled eyes had a myopic shift in refraction after SOR and PE. When UB is used for IOL power calculation, better refractive outcomes are obtained when SOR and PE are performed in a two-step approach.
CONCLUSION:: Phacolytic glaucoma can present with a cloudy cornea and a turbid anterior chamber mimicking endophthalmitis. Careful examination and ancillary investigations including ultrasound biomicroscopy was helpful in making an accurate diagnosis. PMID: 30950286 [PubMed - as supplied by publisher]
CONCLUSIONS:: This case is first of its kind in the literature. The role of ultrasound B-scan, anterior segment optical coherence tomography, and Scheimpflug imaging in the preoperative evaluation of capsulolenticular status and subsequent successful management is discussed.

We read with interest the experimental study on the effectiveness of thermoreversible (poloxamer) hydrogels as a substitute for ophthalmic viscosurgical devices (OVDs) during phacoemulsification in porcine and rabbit eyes by Choi et al.1 A significant finding in their in vivo study of rabbits is that after exposure to 5 minutes of intermittent longitudinal ultrasound (US) energy with the bevel up toward the corneal endothelium, the dispersive OVD group had a significantly greater decrease in the endothelial cell count than the 26% poloxamer hydrogel group (mean loss 18.27% versus 5.27%).
Purpose: To evaluate corneal endothelial cell density (ECD) and morphology 2 years after phacoemulsification in subjects from the COMPASS trial (ClinicalTrials.gov, NCT01085357) who had mild-to-moderate primary open-angle glaucoma and visually significant cataracts. Methods: The central corneal endothelium was evaluated by serial specular microscopy at 0 to 24 months. ECD, coefficient of variation, and percentage of hexagonal cells were evaluated by a central image analysis reading center and central corneal thickness (CCT) was evaluated by ultrasound pachymetry. Results: Of 131 subjects who underwent routine phaco...
Abstract OBJECTIVE: To report the intraoperative surgical outcomes and safety of femtosecond laser-assisted cataract surgery (FLACS) during surgeon learning curve and compare those outcomes with those of conventional phacoemulsification in a Canadian public hospital setting. DESIGN: Retrospective chart review. PARTICIPANTS: FLACS and phacoemulsification patients at Brandon Regional Health Centre, Brandon, Manitoba, Canada. METHODS: Intraoperative surgical outcomes and safety (rates of intraoperative complications and phacoemulsification parameters) were compared among 3 groups: the first consecutive...
