Abstract

The objective is to study the astigmatism induced after phacoalternative surgery in order to improve the quality of the surgery. This was a prospective and descriptive cross-sectional study carried out at the Donka University Hospital in Conakry from july 2021 to january 2022, i.e. a duration of 7 months, on 100 operated eyes. It involved 100 eyes, operated by phacoalternative with an upper limbal incision of at least 6 mm and implantation in the lens bag. Automatic refraction was performed pre-operatively and post-operatively at 45ᵉ day. The mean age was 62 years. Visual acuity was reduced to light perception in 58% of cases preoperatively. The mean implant power after biometry was 19±2.38 Dioptres (D); 50% of patients received the calculated implant. Corneal oedema was the most frequent early complication. Regarding the functional outcome, 82% of the eyes had an uncorrected visual acuity greater than 3/10 at D45 and 92% with correction. 95% of preoperative astigmatism was less than 2D and 57% according to the rule. The average postoperative astigmatism induced was 3.15D against the rule. In conclusion, phacoalternative surgery with a linear superior incision induces an astigmatism against the rule of 3.15 dioptres on average.
