Measurement of in vivo lens shapes using IOLMaster 700 B‐scan images: Comparison with phakometry

open access: yesOphthalmic and Physiological Optics, Volume 44, Issue 5, Page 1041-1051, July 2024.
Abstract Purpose This study compared in vivo crystalline lens shape measurements using B‐scan images from the IOLMaster 700 with phakometry. Methods Twenty‐four young adult participants underwent IOLMaster 700 and phakometry measurements under cycloplegia (1% cyclopentolate).

The posterior optic capture as a way to increase the rotational stability of toric intraocular lenses

open access: yesActa Biomedica Scientifica
Background. Implantation of toric IOLs allows to achieve the best visual results in patients with astigmatism. However, even a small dislocation of the toric IOL can significantly reduce the effectiveness of correction.

Selection of keratometric data for the IOL toricity calculation

open access: yesFyodorov journal of ophthalmic surgery, 2023
Purpose. To elaborate the customized principle of determining the actual zone of the corneal astigmatism based on keratotopographic data and compare the accuracy of calculating the toric IOL according to the actual zone and conventional keratometry. Material and methods. The study included 48 patients (48 eyes) who underwent toric IOL implantation.
