Preparation for cataract surgery in patients with keratoconus (KC) is associated with particular challenges: calculating the optical power of the intraocular lens (IOL), selecting the appropriate IOL model, and considering additional interventions aimed at stabilizing KC and reducing irregular astigmatism. This article presents a fundamentally new approach to combined treatment of KC with cataract, consisting of two stages: first, performing bandage therapeutic-optical keratoplasty (BTOK), followed by cataract phacoemulsification as the second stage.

Implementation of SICS (small incision cataract surgery) in humanitarian campaigns: Description of the surgical technique and review of the literature.

The aim of this article has been, on the one hand, to describe the use of MSICS (manual small incision cataract surgery) for the management of cataracts, especially mature ones, in relation to its particular utility in the field of humanitarian campaigns, for which a description of the MSICS technique has been made, subsequently a review of the available scientific literature has been carried out to verify the results of this technique in comparison with phacoemulsification and extracapsular surgery and to describe the importance of teaching this technique to all cataract surgeons, especially the ones participating in humanitarian campaigns. According to what has been found, MSICS is an excellent surgical technique and according to current evidence it seems to be the choice over phacoemulsification and/or the classic extracapsular technique in hyper mature cataracts, especially in the field of humanitarian campaigns, due to its lower rate of complications and the improvement in visual acuity obtained. According to the studies found, it would be possible for the experienced ophthalmologic surgeon to implement this technique since the learning curve is short.

Purpose: To compare the precision of the arithmetic mean of surgically induced astigmatism (M-SIA) and the centroid of surgically induced astigmatism (C-SIA) in estimating SIA when predicting the power and axis of toric IOLs under different circumstances.
Methods: 120 eyes of 99 patients undergoing toric IOL replacement in a simple cataract surgery were included in the retrospective study. The predicted position of toric IOL was calculated by Z Calc online calculator and Barrett Toric Calculator with M-SIA (0.

Unlabelled: The scientific and practical interest in studying the biomechanical characteristics of the lens capsule, on the one hand, is associated with its anatomical significance in modern microinvasive phaco surgery, and on the other hand, with investigation of the mechanisms of lens curvature changes during accommodation. Selective study of the biomechanical properties of the lens capsule aims to identify characteristics of various regions and surfaces of the capsule.
Purpose: This study is a comparative analysis of age-related changes in the biomechanical properties of the anterior (AC) and posterior (PC) lens capsules in humans.

Purpose: This study evaluated the impact of phacoemulsification cataract surgery (PE) on anatomical and functional parameters, as well as the regimen and frequency of anti-VEGF injections in patients with neovascular age-related macular degeneration (nAMD) over a long-term period (up to 3 years).
Material And Methods: The study included 117 patients (117 eyes) diagnosed with nAMD and cataract, graded by LOCS: LOCS I (=56; 47.9%), LOCS II (=57; 48.
