PURPOSE: To evaluate the effect of toric intraocular lens implantation in cataract patients with irregular corneal steep and flat meridian.
METHODS: Data of 112 eyes of 78 patients who underwent toric intraocular lens implantation were analyzed retrospectively. Steep meridian deviations (not 180°) and steep and flat meridian deviations (not 90°) were classified as 0, 1-9, 10-19, 20-29, 30-39, and over 30°. Meridian deviation was measured with a sagittal map of a rotating Scheimpflug camera (Pentacam®: Oculus, Wetzlar, Germany) using PicPickTools (NGWIN, Seoul, Korea).
RESULTS: Residual astigmatism (D) of 0 (0.51 ± 0.13, 0.55 ± 0.15) and 1-9 (0.61 ± 0.16, 0.66 ± 0.19) groups were significantly lower than that of 10-19 (0.92 ± 0.24, 0.90 ± 0.28), 20-29 (0.10 ± 0.32, 1.01 ± 0.35), and over 30° groups (1.12 ± 0.37, 1.14 ± 0.40) both in steep meridian deviations and horizontal and vertical meridian deviations at 6 months (P < 0.05). Postoperative mean UCVA (logMAR) of 0 (0.09 ± 0.04, 0.09 ± 0.05) (logMAR) and 1-9 (0.10 ± 0.04, 0.11 ± 0.08) groups was significantly improved compared to that of 10-19 (0.14 ± 0.05, 0.17 ± 0.10), 20-29 (0.18 ± 0.08, 0.21 ± 0.10), and over 30° groups (0.20 ± 0.09, 0.22 ± 0.11) both in steep meridian deviations and horizontal and vertical meridian deviations at 6 months (P < 0.05).
CONCLUSIONS: Correction of astigmatism with toric intraocular lens implantation is not accurate in corneas with steep meridian deviations and steep and flat meridian deviations of more than 10°. Therefore, care should be taken when we perform toric intraocular lens implantation in patients with irregular corneal meridian.
