Abstract
Aim: To investigate the visual and refractive outcomes, safety, efficacy and stability of cataract surgery in eyes with stable keratoconus.
Methods: 17 eyes (10 patients) diagnosed as stable keratoconus, aged from 34 to 73 years (56.63±12.47), underwent micro-incision cataract surgery (MICS) followed by implantation of toric intraocular lens (IOL). Seven of them were operated bilaterally and three unilaterally. A complete ophthalmological examinationwas performed preoperatively and postoperatively. The main outcome measures were: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry and manifest refraction.
Results: Sphere changed from −1.77±6.57D (−11.00 to 7.00) preoperatively to 0.08±0.79D (−1.25 to 1.75) postoperatively (p=0.211), and cylinder changed from −2.95±1.71D (−7.00 to −0.75) to −1.40±1.13D (−3.25 to 0.00) ( p=0.016). UDVA (logMAR) changed from 1.33±0.95 (0.40 to 2.77) to 0.32±0.38 (0.00 to 1.30) (p=0.008) and CDVA (logMAR) changed from 0.32±0.45 (0.01 to 1.77) to 0.20±0.36 (−0.03 to 1.30) (p=0.013). Efficacy and safety indexes were 1.38±0.58 and 1.17±0.66, respectively. Refraction and corneal topography were stable during the follow-up (9.10±5.54 months, 3–15).
Conclusions: MICS surgery using corneal topography data and standard formulas for the calculation of the IOL power is a safe and effective procedure regarding keratometric stability, visual and refractive results.
