Microincision cataract surgery (MICS) has been shown to induce less astigmatism.1 We compared the changes in corneal shape in each patient with an intraindividual comparison of each Zernike corneal aberrations and studied the correlation between pre- and postoperative aberrometric measurements, hoping to evaluate corneal integrity after MICS.
This prospective clinical study included 29 consecutive eyes with 1.8 mm MICS (same surgeon, PJP). Exclusion criteria were a previous ocular surgery, central endothelial cell count less than 1800 cells/mm2, ocular surface pathology, glaucoma or topical treatment. Two limbal incisions of 1.8 mm (at the 10.30 o'clock position) and 1 mm (at 2 o'clock) were created with a steel blade. A 5 mm continuous curvilinear capsulorhexis was done, and the nucleus was removed with a 0.95 mm 30° angled tip, using a continuous ultrasound setting (Stellaris, Bausch …
