PURPOSE: To investigate the association between senile corneal arcus and atherosclerosis risk factors in patients with recent acute myocardial infarction. METHODS: In this cross sectional study, atherosclerosis risk factors including fasting blood sugar, total cholesterol and triglyceride levels were measured in 165 patients with recent (less than three months' duration) acute myocardial infarction. Slitlamp examination was performed to detect corneal arcus. Associations between senile corneal arcus and atherosclerosis risk factors were assessed...

Siamak Zarei-Ghanavati, Mehran Zarei-Ghanavati
Herein we describe a technique for management of large inadvertent full-thickness trephination during deep anterior lamellar keratoplasty using the big-bubble technique without converting to penetrating keratoplasty. First, the anterior chamber is formed with an ophthalmic viscosurgical device (OVD). Then, the full-thickness wound is secured with one X-type 10-0 nylon suture. A 27-gauge needle is attached to a 2 ml air-filled syringe and inserted into the corneal stroma in the meridian opposite to the site of full-thickness trephination...

AIMS: To evaluate the accuracy and applicability of Plusoptix photoscreener in screening pre-verbal children at risk of amblyopia. METHODS: In this cross-sectional population-based study 996 children aged 6-36 months were screened with the Plusoptix. The children underwent complete examinations that included a manual cycloplegic retinoscopy, slit lamp examination, cover test, the Hirschberg test and an assessment of fixation pattern. In addition, the prevalence of amblyogenic risk factors was estimated, the Plusopix measurements were compared with cycloplegic retinoscopy, and the referral criteria were modified to improve the accuracy of the device...

PURPOSE: To evaluate the clinical outcomes of Artisan phakic intraocular lens (PIOL; Ophtec BV) implantation in patients with stable keratoconus. METHODS: In a prospective, nonrandomized case series, 14 Artisan PIOLs and 2 toric Artisan PIOLs were implanted in 13 patients (16 eyes) with stable keratoconus who had contact lens intolerance. Pre- and postoperative data were collected. RESULTS: Mean follow-up was 14.2 ± 7.8 months. Preoperative uncorrected distance visual acuity (UDVA) was counting fingers in all patients...

AIM AND DESIGN: A retrospective, nonrandomized, single-center clinical study was designed to evaluate the outcomes of corneal collagen crosslinking (CXL) for progressive keratoconus in Iranian patients 12 months after CXL. SETTINGS: This study was carried out at Navid Didegan Eye Center, a private clinic, Mashhad, Iran. MATERIALS AND METHODS: Ninety-two eyes of 53 subjects with progressive keratoconus were evaluated in this study. All eyes completed 1-year follow-up...

Siamak Zarei-Ghanavati, Hamid Gharaii, Mehran Zarei-Ghanavati
We describe a simple method for evaluating the adequacy of the capsule for implantation of a foldable intraocular lens (IOL) during phacoemulsification complicated by a posterior capsule tear. After cortical lens material clean-up and anterior vitrectomy (if required), 3 knots of 10-0 nylon are tied to the trailing haptic of the IOL using a 3/1/1 configuration. Then, the IOL is inserted into the sulcus. If it is unstable when the surgeon tries to deepen or shallow the anterior chamber, gently pulling the nylon thread will prevent posterior IOL dislocation...
