Comparison of Two Modified Sutureless Techniques of Scleral Fixation of Intraocular Lens.

BACKGROUND AND OBJECTIVE

To compare the visual outcome and complications of two different sutureless scleral-fixated intraocular lens (IOL) implantation techniques, that is, intrascleral IOL fixation technique and modified Yamane's technique of scleral fixation of IOL.

PATIENTS AND METHODS

Patients who underwent scleral fixation of IOL (SFIOL) from June 2015 to February 2017 with more than 6 months of follow-up were examined retrospectively. Improvement in visual acuity (VA), intraocular pressure (IOP) measurements, endothelial cell count, central macular thickness (CMT), and intraoperative/postoperative complications were compared at 6 months follow-up.

RESULTS

Seventy eyes were analyzed. The mean follow-up was 10.5 months ± 1.5 months. The final visual outcomes in both groups, modified intrascleral IOL fixation technique (Group A, n = 30) and modified Yamane's technique (Group B, n = 40), were comparable. The indications for surgery were aphakia (n = 15), subluxated/dislocated cataract (n = 31), and dislocated/subluxated IOL (n = 24). The majority of the eyes (92%) improved to VA 0.3 logMAR units or better. The uncorrected distance visual acuity (UDVA), endothelial cell density, and CMT at the 6-month follow-up were comparable in both groups. Postoperatively, transient IOP rise occurred in 18 eyes, retinal detachment in one eye, vitreous hemorrhage in one eye, cystoid macular edema in two eyes, and mild IOL decentration in two eyes.

CONCLUSION

Both techniques have favorable visual outcomes; however, modified 27-gauge needle-assisted Yamane's technique is technically superior because of its transconjunctival approach and less surgical time, and its needle-assisted approach for haptic externalization prevents haptic damage during externalization.
