ABSTRACT

Purpose: To evaluate the benefit of the astigmatome to decrease the residual astigmatism in operated patient after extra capsular cataract extraction.
Patient and methods: Descriptive and longitudinal study, made with an intentional sample of 11 patients. The approaches of selection were that they had been operated of cataract with manual extra capsular cataract extraction plus intraocular lens implant at least 6 months before. All were operated by the same surgeon who used the double blade astigmatome of Terry-Schanzlin with the Schanzlin nomogram. Follow up was given at least 4 months and they were evaluated by visual acuity and keratometric readings.
Results: 10 of 11 eyes improved keratometric and visually (91%), one remains the same. The mean presurgical astigmatism was 3.1 diopters (D) and post surgical 0.9 D. Two perforations were presented in same eye, only one need a 10-0 nylon stitch that were removed 2 weeks after.
Conclusions: Given the reproducibility of their results, it lower rate of complications and high patient satisfaction; we consider safe and easy the use of the astigmatome under maker’s recommendations and good patient’s selection.
