Higher degrees of astigmatism are found after intraocular lens implantation than after routine cataract surgery. The cause is optical and is associated with the effectivity of lenses. The same amount of corneal astigmatism requires, in the spectacle correction, a cylinder that is smaller than, equal to, or larger than the corneal astigmatism, depending on whether the spherical equivalent of the refraction is a plus, zero, or minus sphere.
In a study of 613 Medallion suture implant patients, 87% of the 613 and 96% of those under 70 years of age had a postoperative visual acuity of 20/40 or better. The most common operative complication was corneal endothelial trauma, which was graded and correlated with endothelial microscopy; however, only 0.5% of cases had permanent corneal opacification. Cystoid macular edema occurred in 32 cases (5.2%), and 56% (18) of these patients regained 20/40 vision or better. Implant loop subluxation occurred in 19 cases (3.1%), but this incidence should decrease by increasing implant loop tip-to-tip distance. The data presented put in perspective the relative importance of the various complications encountered, with primary emphasis on the management of these complications.
