In the event of inability to place an intraocular lens in the bag during cataract surgery, fixating the lens to the sclera becomes a viable alternative. Surgical techniques for scleral-fixated intraocular lenses (SFIOLs) have improved over the years as innovative surgeons attempt modifications of existing techniques [1,2]. There are ab-interno and ab-externo techniques during which rigid or foldable IOLs can be used [3]. Some techniques may be associated with exposure of sutures which may cause irritation, delayed healing and poor cosmetic appearance [3]. To ensure adequate suture covering, a conjunctival flap, a scleral flap or a corneal tissue button can be used [4]. The American academy of ophthalmology technology assessment group reviewed various techniques for anterior chamber IOL, scleral fixated PCIOL and iris fixated PCIOL and did not find any compelling evidence to recommend one technique over the other [5]. Common indications for scleral fixation include; posterior capsular rent, weak zonules, traumatic cataracts, and dislocated intraocular lenses. According to the Nigerian blindness and visual impairment survey, uncorrected aphakia is responsible for 15.8% of severe visual impairment and 8.4% of blindness [6].
