Objective: To review the 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 MX60T toric lens implantation. At week one, month one and month three, uncorrected visual acuity (UCVA) 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: Twenty eyes (n = 20) were included. Mean preoperative uncorrected visual acuity (UCVA) was 0.84 logMAR, and at the final visit UCVA was 0.004 logMAR (p <0.0001). Mean preoperative corneal astigmatism was -2.50 diopters; at the final visit mean refractive astigmatism was -0.34 diopters (p <0.0001). Ninety percent 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 relationship between the axial length and the amount of lens rotation (p <0.40). Final UCVA was related to the degree of final astigmatism (p = 0.001). None of the eyes showed glistening or required posterior YAG capsulotomy. Conclusions: The enVista MX60T toric intraocular lens showed good visual results and excellent rotational stability in the mid-term (3 months). Therefore, it can be considered as an excellent therapeutic option in patients with cataract and regular corneal astigmatism.
