Sutureless Intrascleral Posterior Chamber Intraocular Lens Fixation: Analysis of Clinical Outcomes and Postoperative Complications.

ABSTRACT:

Purpose

To report a technique for performing sutureless intrascleral fixation of a posterior chamber intraocular lens (PC-IOL) and analyzing the clinical outcomes and postoperative complications. Study Design. 68 eyes of 66 patients who received the technique were studied retrospectively.

Methods

The best-corrected visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), IOL tilt and decentration, corneal topography (K1 and K2), and postoperative complications were determined at 3 months.

Results

The mean preoperative BCVA was 1.63?±?1.24 logMAR units, and the mean postoperative BCVA was 0.74?±?0.59 logMAR units at 3 months (P < 0.05). The mean preoperative IOP was 21.9?±?12.6?mmHg, and the mean postoperative IOP was 16.9?±?4.5?mmHg at 3 months (P?=?0.001). The mean preoperative corneal topography (K1 and K2) was K1?=?42.14?±?1.91 and K2?=?43.54?±?1.51; the mean postoperative corneal topography (K1 and K2) was K1?=?43.03?±?2.18 and K2?=?43.40?±?1.71 at 3 months (P?=?0.678 and 0.468, respectively). The mean preoperative spherical equivalent was +11.00?±?13.19 diopters (D), and the mean postoperative spherical equivalent was +0.06?±?0.86 D (P < 0.005). The mean IOL tilt was 2.4?±?1.7°, and the mean decentration was 0.35?±?0.21?mm. The mean ACD was 4.31?±?0.29?mm.

Conclusions

The 27-gauge sutureless intrascleral PC-IOL implantation technique minimizes intraoperative injury, simplifies procedure, and provides good PC-IOL fixation with few postoperative complications.

Project description:PURPOSE:To describe surgical outcomes and structural characteristics of intraocular lenses (IOLs) implanted with transconjunctival sutureless intrascleral (SIS) fixation in human eyes. DESIGN:Retrospective interventional surgical case series involving live and cadaveric human eyes. METHODS:In this study, we investigated the surgical outcomes and structural anatomy of secondary IOLs implanted with the SIS technique in human eyes. All cases involving SIS IOL fixation performed at a single academic center from January 1, 2012, through July 30, 2016, were reviewed to describe the surgical technique, common indications, clinical outcomes, and the rate of common operative complications. To investigate the structure of SIS-fixated IOLs in vivo, slit-lamp biomicroscopy, ultrasound biomicroscopy, and intraoperative endoscopy were analyzed to describe anatomical outcomes. The primary anatomical outcomes were the optic pupillary centration and location of haptic externalization. Results were correlated with cadaveric human eyes that underwent the SIS-IOL technique. Cadaveric eyes were imaged and analyzed using high-resolution photography for centration, stress measurements at the haptic-optic junction, and qualitative descriptors of IOL optic and haptic position. RESULTS:A total of 122 consecutive patients who underwent IOL placement using SIS technique were included in the study with mean follow-up of 1.52 years (range, 0.4-4.5 years). The majority (75%) of patients received a new 3-piece IOL for primary aphakia or after IOL exchange. The other patients (25%) had a dislocated 3-piece IOL that was rescued using the SIS technique. Preoperative mean Snellen visual acuity was 20/633 (logarithm of the minimum angle of resolution = 1.501). At the final visit, the mean best-corrected visual acuity was 20/83 (logarithm of the minimum angle of resolution = 0.6243) and final mean spherical equivalent was -0.57 diopters. The most common complications were vitreous hemorrhage (22% of eyes), which resolved spontaneously in most cases, and cystoid macular edema. The rates of IOL dislocation, IOL decentration, haptic erosion, IOL tilting, iris capture, and endophthalmitis were low. Intraoperative endoscopy and ultrasound biomicroscopy demonstrated a securely fixated IOL and well-centered optic without iris or ciliary body touch. Structural study of cadaveric eyes confirmed IOL optic and haptic anatomy observed during live human surgery. The ab interno haptic insertion was the anterior pars plana, away from the iris, ciliary processes and ora serrata. The degree of haptic externalization was correlated with the degree of strain on the haptic-optic junction. The angle of the haptic-optic junction in SIS-fixated IOLs (33.97°) was not significantly different compared with overlaid native nonfixated IOL (32.93°) but increased slightly with degree of haptic tip externalization (36.26 and 39.16 for 2 and 3 mm haptic externalizations, respectively). CONCLUSION:In this comprehensive study, we demonstrate the surgical outcomes achieved with SIS fixation of IOLs. Surgical and postoperative complications do occur, albeit at a low rate, and can effectively be managed with excellent anatomical and visual outcomes. The structural and anatomical data in this study may help guide SIS placement and optimize long-term surgical results.
