ABSTRACT

Objective: To evaluate the visual results and rotational stability of the enVista MX60T TORIC intraocular lens. Methods: A prospective and longitudinal study was carried out, phacoemulsification surgery was performed with the MX60T toric lens implant. At week one, month one and month three, the uncorrected visual acuity (UVA) and spherical equivalent were evaluated. At each visit, the alignment of the toric lens was evaluated using the OPD-Scan III “toric summary” (Refractive Power/Corneal Analyzer, NIDEK®). Results: 20 eyes (n = 20) were included. The mean preoperative uncorrected visual acuity (UVA) was 0.84 logMAR, and at the final visit UVA was 0.004 logMAR (p ‹ 0.0001). The mean preoperative corneal astigmatism was −2.50 diopters, at the final visit the mean refractive astigmatism was −0.34 diopters (p ‹ 0.0001). 90% of the eyes had a final vision of 20/25 or better. The average rotation of the lens was 2.05° with a range of 0-5. There was no relation between the axial length and the amount of rotation of the lens (p ‹ 0.40). The final UVA was related to the degree of final astigmatism (p = 0.001). None of the eyes showed glistening neither required posterior YAG capsulotomy. Conclusions: The enVista MX60T toric intraocular lens showed good visual results and excellent rotational stability in the medium term (3 months). Therefore, it can be considered as an excellent therapeutic option in patients with cataract and regular corneal astigmatism.
