Comparative analysis of two innovative products designed exclusively for sutureless scleral fixation of intraocular lenses, "XNIT device" versus "CM-T flex intraocular lens".

Purpose: To compare the safety and efficacy of two innovative products for sutureless scleral fixation of intraocular lenses (SFIOL), namely, extraocular needle-guided haptic insertion technique (XNIT) device and CM-T Flex IOL.

Setting: This study was conducted at two different tertiary eye hospitals in South India.

Design: Nonrandomized comparative-retrospective study.

Methods: A retrospective analysis of 137 eyes of 137 patients was done, in which 80 eyes underwent SFIOL using XNIT technique and 57 eyes used the CM-T flex IOL. Visual outcomes and complication rates were evaluated over a 6-month follow-up period.

Results: At 6 months, the XNIT group demonstrated superior median best-corrected visual acuity (BCVA). Both techniques showed comparable BCVA at 1 and 3 months follow-up visits. XNIT group showed better uncorrected visual acuity at all study visits. There were no statistically significant differences between two techniques in postoperative complication rates.

Conclusion: In conclusion, both XNIT and CM-T Flex techniques represent advancements in SFIOL surgery, each with distinct advantages. Clinicians should consider patient-specific factors and surgical preferences when choosing between these techniques for optimal outcomes in aphakic management.
