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.
