AIM: To determine corneal astigmatism in patients with cataract posted for surgery. To achieve good visual outcome, significant corneal astigmatism has to be taken care of at the time of surgery either by corneal or limbal relaxing incisions or by implantation of toric intraocular lens. MATERIALS AND METHODS: This is a prospective observational case series conducted on 200 patients with cataract who attended the out-patient department of ophthalmology and consented for investigations and surgery. Keratometry readings were recorded along two principal corneal meridians using Bosch and Lomb Keratometer. RESULTS: Against the rule astigmatism is found to be more common than with the rule astigmatism, more so as age advances. Most of the patients had less than 1D of astigmatism. CONCLUSIONS: The younger the patient is, the lesser the chances of developing astigmatism. Amblyogenic astigmatism is very rare.
