Abstract Details


To evaluate clinical outcomes following toric intraocular lens (IOL) implantation in patients with cataract and keratoconus.


University Eye Clinic Maastricht, the Netherlands.


Sixteen patients (25 eyes) with stable mild to moderate keratoconus (Krumeich stage 1 and 2) underwent cataract surgery with toric IOL implantation (Acrysof SN6AT3-T9 or Rayner T-flex). Postoperatively uncorrected and best-corrected distance visual acuity (UDVA and BDVA), subjective refraction, Alpins vector analysis, surgically induced corneal astigmatism, posterior corneal astigmatism and IOL misalignment were evaluated.


Mean follow-up was 3 ±2 months . Preoperative BDVA was 0.36 ±0.16 LogMAR and corneal astigmatism 3.79 ±1.36 D (range 1.42–6.38 D). Postoperatively, UDVA and BDVA were 0.17 ±0.15 LogMAR and 0.10 ±0.10 LogMAR, respectively. Residual refractive astigmatism was -1.24 ±0.94 D and 52% of eyes achieved a refractive astigmatism of 1.0 D or less. Surgically induced corneal astigmatism was -0.22 ±0.62 D @ 136 degrees. The mean magnitude of posterior corneal astigmatism was -0.66 ±0.27 D. The mean correction index of 1.17 and magnitude of error of 0.34 D both indicate a general overcorrection. In 3 eyes, a realignment was performed.


Cataract surgery with toric IOL implantation is an effective treatment option in patients with mild to moderate, stable keratoconus. However, care should be taken to prevent overcorrection.
