Question 83

Preoperative measurements on your next cataract patient show 2.50 diopters of corneal astigmatism at 180 degrees. You select a toric intraocular lens (IOL) that will leave a residual of 0.40 diopters at 180 degrees. The surgery is complicated by floppy iris. Post operative day #7, the patient's refraction shows 3.50 diopters of astigmatism at 025 degrees. Why did the astigmatism increase?

Toric IOL was inserted upside down

Toric IOL was inserted into the sulcus

Toric IOL was inserted 30 degrees off axis

Toric IOL was inserted 60 degrees off axis
