PURPOSE To assess the accuracy of corneal astigmatism evaluation measured by four techniques, Orbscan IIz(®), Lenstar LS900(®), Cassini(®), and Total Cassini (anterior + posterior surface), in pseudophakic eyes. PATIENTS AND METHODS A total of 30 patients (46 eyes) who had undergone cataract surgery with the implantation of a monofocal intraocular lens (AcrySof IQ) were assessed after surgery...

Purpose of the paper was to evaluate ocular optical components (OOC) interactions in a large number of emmetropes. A cross-sectional study of 1,000 emmetropes, aged from 18-40 years, has been conducted. Complete ophthalmological examination, corneal radius (CR) measurement, keratometry and echobiometry of both eyes were performed. The highest correlation of OOC was that of axial length (Ax) wit...

PURPOSE To assess astigmatism induced by paired opposite clear corneal incision (OCCI) compared to single incisions and to investigate factors on which its effect depends. METHODS The study comprised 326 eyes from 326 patients. In patients with <1.0 D corneal astigmatism, clear corneal incision was performed (CC group, n = 245), and in those with >1.0 D preoperative corneal astigmatism, a sec...

purpose : to compare results of different methods for true corneal power determination and intraocular lens (iol) power calculation formulas in 10 eyes of 7 patients with previous radial keratotomy (rk) with or without astigmatic keratotomy methods : in this case series study, we determined the corneal power of 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy wit...

purpose: to report the results of different methods for true corneal power and intraocular lens (iol) power calculation in 10 eyes with previous radial keratotomy (rk) with or without astigmatic keratotomy. methods: in this case series including 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy, we firstly determined corneal power using two methods: contact lens m...

The current article illustrates neuroanatomical neurophysiological fundamentals mechanisms manual diagnostics treatment. Based on recent literature consideration different scientifically based clinical guid...

AIM To evaluate the visual outcomes of simultaneous non-topography guided photorefractive keratectomy (PRK) and corneal collagen cross-linking (CXL) in eyes with keratoconus 5y after the procedure. METHODS Prospective, interventional, non-randomized, and non-controlled case series design was used. Sixty eyes of 30 patients (16 males and 14 females; age: 21-41y) with mild, non-progressive (sta...
