Scleral Tunnel Fixated Intraocular Lens in Complicated Cataract: A Case Series

Abstract

When capsular support is inadequate in complicated cataract, scleral fixated IOL (SFIOL) has its advantage whereby it is nearer to physiological nodal point when compared to other types of IOL implantation. Scleral tunnel fixated intraocular lens (STFIOL) technique is gaining popularity due to its simplicity and ease of placement compared to sutured IOL. We report our experience with eight cases of STFIOL implantation from September 2016 to May 2018 in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). All patients had improvement of vision except one case who had unchanged vision. Mean post-operative BCVA was logMAR 0.57±1.13 (which is almost equivalent to 6/21) and improved to logMAR 0.37±0.43 (which is almost equivalent to 6/12) excluding one patient with chronic RRD with band keratopathy. Post-op complications include raised intraocular pressure, cystoid macular oedema, hyphaema, and wound leak. However, all complications were not severe and responded to topical eyedrops. In conclusion, STFIOL insertion technique is safe and works well to restore vision in majority of patients operated with this technique.
