Patients often ask about correction astigmatism at the time of cataract surgery. In europe patients can now have sophisticated intraocular lenses called toric lenses that correct astigmatism at the time of cataract surgery. These lenses often have to be ordered ahead of time and are manufactured to the patients specifications.
If you are having a toric lens your surgeon will make some small marks on your eye to indicate the horizontal and vertical axis of the eye. The exact angle of astigmatism is then marked when you are on the operating table. Cataract surgery is completed in a standard fashion. The toric lens is then injected into the eye and the surgeon will then carefully align the lens to the correct axis of astigmatism. This is aided by small alignment marks on the lens. The video shows the procedure.
