Purpose
To analyze the effectiveness of refractive lensectomy with implantation of Clareon Toric IOL (Alcon) in patients undergoing simultaneous surgery for vitreomacular interface pathology.
Setting
This study was conducted at a specialized ophthalmic surgical center, where patients with early peripheral cataract, ametropia, astigmatism, and vitreomacular pathology underwent refractive lensectomy with Clareon Toric IOL (Alcon). Experienced surgeons used standardized techniques and biometric planning tools, including the Barrett Online Calculator. Comprehensive ophthalmologic assessments, including visual acuity, keratorefractometry, and SD-OCT, were performed pre- and postoperatively.
Methods
A total of 34 patients (34 eyes) underwent refractive lensectomy (removal of a clear crystalline lens), followed by implantation of Clareon Toric IOL (Alcon) in combination with surgery for vitreomacular interface pathology. The mean patient age was 66.42 ± 7.28 years. Preoperative parameters included UCVA of 0.19 ± 0.13, BCVA of 0.5 ± 0.2, spherical refraction of -0.40 ± 1.85 D, cylindrical refraction of -1.16 ± 1.36 D, corneal astigmatism of -1.52 ± 0.76 D (ranging from 0.75 D to 3.25 D), axial length of 24.36 ± 1.55 mm, and maximum retinal thickness of 426.94 ± 72.42 μm. IOL positioning was planned using the Barrett Online Calculator. The following Clareon Toric IOL models were implanted: CNW0T2 – 9.
Results
Three months postoperatively, UCVA significantly improved to 0.7 ± 0.24 (p < 0.005), exceeding preoperative BCVA, which also improved to 0.79 ± 0.16 (p < 0.005). Spherical refraction shifted toward emmetropia (0.08 ± 0.57 D, p < 0.005), and cylindrical refraction decreased (-0.4 ± 0.52 D, p < 0.005). Maximum retinal thickness reduced to 306.29 ± 72.42 μm (p < 0.005).
Conclusions
Implantation of Clareon Toric IOL (Alcon) in patients undergoing combined cataract and vitreomacular interface pathology surgery provides predictable refractive outcomes and significant visual function improvement. Stable IOL positioning was confirmed by reduced residual astigmatism. Astigmatism correction in combined surgery enhances patients’ quality of life and reduces dependence on spectacle correction.
