Endoscope-Assisted Sutureless Intrascleral Haptic Fixation of a Posterior Chamber Intraocular Lens

In eyes with compromised capsule support, sutureless scleral fixation is a popular method of placing a posterior chamber intraocular lens (PCIOL). We describe an endoscope-assisted sutureless technique for intrascleral fixation of a 3-piece PCIOL.

Eyes of patients who had endoscope-assisted scleral-fixated intraocular lens (SFIOL) implantation were examined retrospectively. The technique comprised direct capture of the IOL haptic with a forceps through a pars plana sclerotomy with subsequent haptic fixation into scleral tunnels created with a 26-gauge needle. The endoscope was used to visualize haptic positioning under the iris and ensure proper centration of the IOL.

Thirteen eyes of 13 patients were examined. The mean age of the patients was 68.2 years (range, 38-87 years), and the mean follow-up was 13.6 months (range, 5-23 months). The indications for surgery were a subluxated IOL (6 eyes), postoperative aphakia (5 eyes), and a subluxated cataract (2 eyes). The mean best-corrected visual acuity ± SD improved significantly from 1.2 ± 0.6 logMAR preoperatively to 0.6 ± 0.7 logMAR at last the follow-up (paired Welch t test; t₁₀ = 2.69; P = .023). IOL stability and centration were maintained in all patients.

Endoscopic visualization during sutureless SFIOL implantation helped improve haptic localization, minimize intraoperative complications, and achieve excellent IOL centration.
