Purpose: To investigate the causes of Implantable Collamer Lens (ICL) explantation and study the visual outcomes after further management in a retrospective case series. Methods: Retrospective chart review was performed for all the eyes that underwent bilateral or unilateral ICL explantation between March 2010 and April 2015. Incidence & causes of explantation, time between primary & secondary ...

PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation using conventional regression formulae or the American Society of Cataract and Refractive Surgery (ASCRS) IOL power calculator for previous corneal refractive surgery. METHODS We retrospectively reviewed 96 eyes from 68 patients that had undergone cataract surgery after keratorefractive surgeries. We calculated the fo...

Astigmatism represents an inability of the cornea and lens to provide a sharp image onto the retina. Correcting astigmatic errors, whether congenital, contact lens induced or surgically induced, is now an integral part of modern cataract and refractive procedures. Development of modern technology has enabled accurate diagnosis and perfect opportunities for correction; however, while cataract an...

purpose: to evaluate agreement between galilei, orbscan ii, and placido disk-based topography in terms of keratometry readings, and anterior and posterior elevation. methods: in this prospective comparative study, 184 eyes of 92 keratorefractive surgery candidates were evaluated with galilei, orbscan ii, and placido disk-based topography. keratometry readings and anterior and posterior elevatio...

Purpose. Scientific substantiation of methodological approaches to the development a “quality life” (QoL) questionnaire after cataract phacoemulsification (PEC) in patients with visually stressful work (VLT), based on “medico-social” health model. Methods. The study was carried out basis standards for new tools assessing symptoms clinical medicine developed by specialists from International Cen...

In vivo confocal microscopy (IVCM) is an emerging technology that provides minimally invasive, high resolution, steady-state assessment of the ocular surface at the cellular level. Several challenges still remain but, at present, IVCM may be considered a promising technique for clinical diagnosis and management. This mini-review summarizes some key findings in IVCM of the ocular surface, focusi...

The main objective of refractive surgery is improving the patient’s quality of life by decreasing their dependence on spectacles and contact lenses. In the majority of cases, we, refractive surgeons, are dealing with young healthy individuals with excellent quality of vision; they are seeking no less than excellent uncorrected visual acuity with at least the same quality of vision postoperative...
