Abstract

Objective: To analyze the enduring rotational steadiness of AcrySof IQ Toric intraocular lens (IOL) in cataract patients suffering from myopia in a long-term study. Methods: A retrospective study was conducted on a case series involving 78 patients. A total of 120 eyes with an axial length (AL) ranging from 24–30 mm and corneal astigmatism ≥ 1.50 D underwent implantation of AcrySof IQ Toric IOL guided by the version navigation system. The eyes were divided into two groups based on AL. Group A included 60 eyes with high myopia (AL ≥ 26 mm), while Group B consisted of eyes with low to moderate myopia (24 mm ≤ AL < 26 mm). Data on the preoperative AL were collected. Measurements were taken for residual astigmatism, the best corrected visual acuity (BCDVA), corneal astigmatism, and IOL rotation occurring between 24- and 48-months post-surgery. The percentage of eyes with an IOL rotation of under 5° and 10° was analyzed. Results: The mean length of follow-up times was recorded as 34.27 ± 4.98, and the average rotation was 2.73 ± 1.29°. Group A exhibited a slightly higher average rotation of 2.87 ± 1.31°, compared to the rotation of 2.59 ± 1.27° observed in Group B. At both the 24–36 month and 26–48 month post-operation marks, the degree of IOL rotation did not show a statistically significant difference between the two groups, with none of the patients experiencing a rotation exceeding 10° (P > 0.05). The percentage of rotation degrees under 5° was recorded as 98.22%. After the procedure, the BCDVA was 0.13 ± 0.03 LogMAR. There was a substantial increase in the χ2 value after the operation as compared to the pre-operative χ2 value (χ2 = 76.79). The standard deviation of preoperative corneal astigmatism was statistically significant (P < 0.05) at 2.17 ± 1.08 D. Following the surgical procedure, the remaining astigmatism was measured at 0.41 ± 0.26 D. The data showed a notable gap in statistical significance (t = 4.281, P < 0.05). Conclusion: The AcrySof Toric IOL was a reliable solution for managing corneal astigmatism in cataract patients with myopia, demonstrating excellent long-term rotational stability.
