In this case series, we assessed a new technique, the intrascleral pocket procedure of transscleral fixation(TF) of the intraocular lens (IOL) in post-vitrectomized eyes. We performed the transscleral fixation of IOLin four aphakic patients who underwent pars plana vitrectomy. Two points 180° apart were marked at thelimbus. A 2-mm-sized intrascleral pocket was created by lamellar dissection using a crescent blade withoutconjunctival dissection. A 2.8-mm clear corneal incision (CCI) was made using a keratome. Prolene sutureswere exteriorized through the CCI pocket and a three-piece foldable acrylic IOL was injected via CCIand the ends of the haptics were exteriorized through the CCI. The prolene sutures for each haptic in theintrascleral pocket bed were then tied and knots were buried under scleral flaps. No patient had complaintssuch as conjunctival irritation, and visual acuity was almost identical to preoperative best-corrected visualacuity at day 1 postoperatively. IOLs were well placed without tilting or subluxation. They had no wounddehiscence or endophthalmitis postoperatively. The intrascleral pocket procedure of TF without the needfor conjunctival dissection is a successful method for sulcus fixation in post-vitrectomized eyes predisposedto developing glaucoma.

A 2-mm-sized intrascleral pocket was created by lamellar dissection using a crescent blade withoutconjunctival dissection. A 2.8-mm clear corneal incision (CCI) was made using a keratome. Prolene sutureswere exteriorized through the CCI pocket and a three-piece foldable acrylic IOL was injected via CCIand the ends of the haptics were exteriorized through the CCI.
