PURPOSE To quantify the effect of small incision lenticule extraction (SMILE) on the corneal biomechanics using Scheimpflug noncontact tonometer (Corvis ST). METHODS Twenty eyes of twenty patients, evaluated as eligible for surgery, with high myopia and/or moderate myopic astigmatism, underwent small incision lenticule extraction (SMILE). All patients underwent Corvis ST preoperatively and po...

purpose : to compare the outcomes of coaxial microincision phacoemulsification with that of conventional coaxial phacoemulsification setting: department of ophthalmology, farabi and noor eye hospitals, tehran, iran methods : in a prospective study, 74 eyes of 74 patients with cataract were randomly selected to have cataract extraction using 1 of 2 techniques: coaxial microincision phacoemulsifi...

Deep lamellar endothelial keratoplasty (DLEK) has become an alternative procedure for bullous keratopathy. Herein, the histopathological characteristics of corneal wound healing after DLEK were reported. A 71-year-old man suffering from left psuedophakia bullous keratopathy received small incision DLEK. Twenty months later, another penetrating keratoplasty (PK) was performed because of the graf...

PURPOSE To use Fourier-domain anterior segment optical coherence tomography (AS-OCT)) to evaluate the main clear corneal incisions (CCIs) in microcoaxial and biaxial cataract surgery, the effects of incision enlargement, and the probable reasons for problematic healing. SETTING Atatürk Training and Research Hospital, 2nd Ophthalmology Department, Ankara, Turkey. DESIGN Cohort study. METHO...

PURPOSE To determine whether Hartmann-Shack wavefront sensing detects differences in optical performance in vivo between poly(methyl methacrylate) (PMMA) and foldable acrylic intraocular lenses (IOLs) and between clear corneal and scleral tunnel incisions and whether optical differences are manifested as differences in visual performance. SETTING Department of Optometry, University of Bradfor...

791 pression of the optic nerve has also been recommend­ ed, but it should be performed within 24 hours and its effectiveness is not clear [3]. Papillary mydriasis occurring during the treatment of blow out fracture might indicate irreversible blindness, because it means that the ciliary ganglion or short ciliary nerves are injured [4]. The ciliary ganglion is located posterolateral to the glob...

To the Editor: Femtosecond laser platforms used for cataract surgery are integrated with anterior-segment optical coherence tomography (AS-OCT), allowing for real-time imaging and measurement of the cornea, possibly leading to more precise arcuate keratotomies.1 The femtosecond laser permits creation of either anterior penetrating incisions or intrastromal incisions. The advantages of intrastro...

One of the drawbacks of all classical incisions for cataract surgery has been the slow consolidation of the scar. According to Dunnington (1956) and to Ashton and Cook (1951), the first step in the healing of limbal wounds is taken by the swelling of the corneal lamellae, whereas the sclera plays a very passive role in the process. The retractability of the tissues then leads to a separation of...
