Abstract

The purpose of this study was to perform a systematic review of existing literature on OCT screening before cataract surgery. Available literature was evaluated and projections on how it could be applied to enhance postoperative outcomes of cataract surgery were summarised. The PubMed, Embase and Cochrane databases were searched for articles pertaining to preoperative OCT screening. Selected articles were qualitatively and quantitatively analysed. Across 9 studies, the addition of OCT macular screening resulted in preoperative detection of macular pathology in 13.7% of eyes that were determined to be normal on fundoscopic examination alone. The types of macular pathology most frequently detected through preoperative OCT screening were interface abnormalities followed by macular degeneration. Comparative analysis of SS-OCT biometer and SD-OCT found that SS-OCT had a sensitivity of 0.48-0.81 in the detection of macular pathology in eyes with pathology diagnosed by SD-OCT. OCT screening prior to cataract surgery results in the detection of occult macular pathology that may influence postoperative visual outcomes in approximately 1 in 10 eyes (13.7%). As a result, OCT screening should be considered in the routine preoperative workup for cataract surgery.
