Accuracy Of Swept Source Biometry Device In Detecting Macular Diseases Compared With Swept Source Oct, Sidra Zafar, Taha Muneer Ahmed, Rashid Baig, Irfan Jeeva, Rehman Siddiqui

Department of Ophthalmology & Visual Sciences

Objective: To assess the diagnostic accuracy of the IOLMaster 700 foveal scans to detect foveal pathology compared with a standard swept-source optical coherence tomography (SS-OCT) device.
Results: One hundred seventy eye scans of 95 patients were included in the final analyses. Ninety-nine (58.2%) scans were classified as abnormal by SS-OCT. Mean sensitivity of the biometry device was 67.5% (range: 51-84%) and mean specificity was 69.5% (range: 44-95%). Intra-class correlation coefficients were 0.912 and 0.835, for reader 1 and 2, respectively. Area under the curve for receiver operating curve was 0.726. Foveal scans of the IOLMaster 700 can provide clinically useful …

Department of Surgery

Abstract

This single group cohort study, undertaken at Aga Khan University Hospital, Karachi, from Jan 2012 to September 2013, assessed patients' satisfaction, spectacle independence and visual disturbance after implantation of multifocal IOLs. A total of 39 patients who underwent bilateral cataract surgery with multifocal IOL implantation were included for telephonic interviews. The mean age of participants was 55.5 ± 8.1 years. The mean follow up time was 9.60 ± 3.19 months. The overall satisfaction rate after surgery was found to be 84.6% and there was no statistically significant association of satisfaction with gender, age or education. In all 84.6%, 94.9% …

bstract

The aim of this study was to assess whether the visual outcome of cataract surgery in the institution was in accordance with the World Health Organization recommendations. In this retrospective case series, all patients who underwent cataract surgery by a single surgeon from January 2009 till June 2011 were included. Date were collected from medical records on age, gender, visual acuity and causes of sub-optimal outcome. The main outcome was best-corrected visual acuity in the operated eye, measured 4 - 6 weeks after surgery. Data on visual outcome was grouped using WHO's classification. Of the 495 eyes that underwent …

Knowledge Of Patients' Visual Experience During Cataract Surgery: A Survey Of Eye Doctors In Karachi, Pakistan, Mohammad Zain Tauqir, Tanveer Anjum Chaudhry, Sehreen Mumtaz, Khabir Ahmad

Department of Surgery

Abstract

BACKGROUND:

Several recent studies have recommended that ophthalmologists must be aware of the visual sensations (and their associated anxiety/fear) experienced by patients undergoing cataract surgery. We assessed the knowledge of a group of eye doctors in Pakistan regarding these phenomena.

METHODS:

This was a cross-sectional survey. Eye doctors (ophthalmologists, residents and medical officers) attending the Ophthalmological Society of Pakistan Annual Conference 2011, in Karachi were invited to participate in the study. A self-administered structured questionnaire was used to examine their knowledge of visual sensations and their associated anxiety/fear experienced by patients during cataract surgery. Simple frequencies and proportions were …
