Modified Intrascleral Fixation for Repositioning the Dislocated Single-Piece, Rigid PMMA Intraocular Lens

imagePurpose:

To describe a modified intrascleral fixation technique for repositioning single-piece rigid polymethyl methacrylate intraocular lenses (IOLs).

Methods:

Four patients with dislocated IOLs were enrolled. Surgical modifications included using ≤1-mm scleral incision for haptic externalization, placing the IOL haptic placement in scleral tunnels, and using 8-0 absorbable sutures. Patients were followed up for 6 months with routine ophthalmic examinations, corneal endothelial cell counts, and ultrasound biomicroscopy (UBM).

Results:

The mean follow-up time was 13.5 ± 5.45 months. The IOL was well centered and the spherical refraction improved (+10.25 ± 2.21 vs. −0.81 ± 1.59 D, P

8-0 Polypropylene Suture Looping and Overhand Knot: Transconjunctival Approach to Four-Point Scleral Fixation of an Akreos Adapt Intraocular Lens

imagePurpose:

To evaluate a novel surgical technique for transscleral fixation of the intraocular lens (IOL) with four hollow haptics using 8-0 polypropylene suture looping and overhand knot.

Methods:

An 8-0 polypropylene suture was tied to a 10-0 polypropylene suture with an overhand knot. One set of 8-0 polypropylene suture was then passed through the IOL four haptics. The suture knot was buried by rotating into the sclera tunnel. Best-corrected visual acuity, intraocular pressure, and complications were determined.

Results:

The IOLs were fixed with using an 8-0 polypropylene suture in 13 eyes of 11 patients with aphakia and dislocated crystalline lens. The mean preoperative corrected distance visual acuity was 0.71 ± 0.58 logarithm of the minimum angle of resolution (Snellen 20/103), and it improved to 0.24 ± 0.25 logarithm of the minimum angle of resolution (Snellen 20/35) at the final follow-up (P
