![]() ![]() Indigenous female patients undergoing cataract surgery were significantly younger compared to non-Indigenous females (62.2 years ± 9.1 versus 71.7 years ± 8.8). Results: Mean age was 65.2 ± 11.1 years, 53.7% (n = 169) were male and 49.8% identified as being Indigenous. ![]() All cases were performed in 2017 by the Lions Outback Vision service, in 7 surgical centres across rural Western Australia. Methods: In a retrospective observational study, an independent observer assessed the clinical data of 366 cases of phacoemulsification surgery. Purpose: To assess the demographic profile, waiting times and clinical outcomes of a public cataract surgery service in rural specialty training in Western Australia. Lions Outback Vision, Lions Eye Institute, Perth, Australia PHACOEMULSIFICATION CATARACT SURGERY AUDIT IN RURAL WESTERN AUSTRALIA PATIENT DEMOGRAPHICS AND CLINICAL OUTCOMESĪisling Mc Glacken-Byrne, Angus Warwick Turner We believe that these results may be incorporated into future evidence based guidelines with regard to the diagnosis and management of PCME. A 44.10 ± 5.22% mean of differences was observed ( P 320 microns was not congruent to achieving postop CDVA of 6/6 or better.Ĭonclusions: Using the patients visual acuity measurement once PCME developed combined with definite central retinal thickness OCT set-points one can estimate the visual potential in patients with clinical PCME. The mean percentage PE, comparing between eyes of different axial lengths, was 9.88 ± 3.48% and −34.9 ± 4.79% for predictions derived from for ACD+½LT and ACD respectively. Results: An overall reduction in average ELP prediction error (PE) was achieved using the proposed parameter (RMSE = 0.50 mm), compared to ACD (RMSE = 1.57 mm). The accuracy and reliability of ELP predictions derived from ACD and ACD+½LT were compared using software-aided analyses. Pre- and post-operative biometric measurements were made using the IOLMaster700 (ZEISS, Jena, Germany). Method: This retrospective study includes data from 162 consecutive cataract surgery cases, with posterior-chamber IOL (AlconSN60WF) implantation. Accordingly, we propose that predictions derived from ACD+½LT would be superior to those from ACD alone. ![]() We hypothesize that predictions based on the distance from the corneal apex to the midsagittal plane of the cataractous lens, would more accurately reflect the position of the principal plane of the non-angulated IOL within the capsular bag. This study aims to improve the predictability of ELP. Significant discrepancies between predicted and actual ELP result in refractive surprise. Latest-generation formulae use Anterior Chamber Depth (ACD) -the distance from the corneal apex to the anterior surface of the lens -to predict the postoperative IOL position within the eye, termed the Effective Lens Position (ELP). Purpose: Achieving the desired post-operative refraction in cataract surgery requires accurate calculations for intraocular lens (IOL) power.
