Glaucoma surgery and induced astigmatism: a systematic review.

摘要: The refractive outcomes of glaucoma surgeries, particularly their effect on astigmatism, are incompletely understood. Trabeculectomy is associated with a considerable amount with-the-rule astigmatic change in the immediate postoperative period. This followed by gradual against-the-rule shift. These changes altered use mitomycin C (MMC). Non-penetrating surgery such as deep sclerectomy also similar or smaller degree induced astigmatism. Minimally invasive appears to be astigmatically neutral. There no clear evidence regarding drainage device surgery. Induced astigmatism may account for reduction unaided visual acuity early period following successful trabeculectomy. appear stabilise at 3 months, and it would prudent defer prescription new glasses until this time. If sequential cataract performed, toric intraocular lenses can useful option correction.
