Lens Displacement And Refractive Outcomes In Eyes Implanted With Clareon Toric

To investigate the correlations between residual cylinder and lens centering and rotation with a new intraocular toric lens: the clareon toric.

single-arm prospective study

Patients with senile cataract (55 up to 85 years of age) and formal indication for phacoemulsification and implant of a toric intraocular lens, due to regular corneal astigmatism between 1 and 4 diopters.

Standard cataract surgey with verion-assisted lens alignment will be performed.

Lens displacement and rotation will be mesured on OPDScanIII (Nidek) usign the retroilumination picture.

Visual acuity and refraction will be assessed 3 months after surgery.

So far, 30 patients were included. Mean preoperative corneal astigmatism was 1.72 ± 0.81 D (Range 1 to 4 D). Mean postoperative astigmatism magnitude was -0.55 ± 0.32 S (Range O to 1 D). lntraocular lens rotation - between intraoperative and postoperative position was 5 ± 4 degrees.

This data shows that lhe new clareon toric is effective for astigmatism correction. Correlation between lens displacement and postoperative residual astigmatism will be investigated.
