Evaluation of a New Monofocal Intraocular Lens in Patients Undergoing Cataract and Vitrectomy Surgery for Idiopathic Macular Hole.

Purpose: To evaluate the usefulness of a newly generated monofocal intraocular lens (IOL) in patients who underwent combined cataract and pars plana vitrectomy (PPV) surgery for idiopathic macular hole (MH).

Methods: A prospective study was conducted on 89 eyes of 89 patients who underwent combined cataract and PPV surgery for MH. The patients were divided into two groups: Eyhance ICB00 and Tecnis ZCB00. Pre-operative characteristics, post-operative visual outcomes, contrast sensitivity, and complications were compared between the two groups. A univariate regression analysis was performed to identify the factors that may affect the postoperative visual outcomes.

Results: Both groups showed significant improvement in mean corrected distance visual acuity (CDVA) six months post-operation (p < 0.001). There was no significant difference in pre-operative characteristics or complications between the two groups. However, the Eyhance ICB00 group showed a significantly higher uncorrected intermediate visual acuity (UCIVA) value at 6 months after surgery than the Tecnis ZCB00 group (p = 0.014). Contrast sensitivity values were not significantly different between the two groups. The univariate regression analysis revealed a significant correlation between preoperative CDVA and minimum linear diameter of MH with postoperative UCIVA in the Eyhance ICB00 group.

Conclusions: The newly generated Eyhance ICB00 IOL showed promising results in terms of post-operative UCIVA, with no significant difference in complications or contrast sensitivity values compared to the Tecnis ZCB00 IOL. These findings suggest that the Eyhance ICB00 IOL may be a useful option for patients who undergo combined cataract and PPV surgery for idiopathic MH, particularly for those who require intermediate visual acuity.
