[Evaluation of application of transparent keratoscope in ocular microsurgery]

The clinical effects of application of a transparent keratoscope in cataract extraction and intraocular lens implantation were reported. The patients were divided into 2 groups: 1 group without and the other group with the application of a transparent keratoscope to control the corneal curvature by regulating the strength of the continuous suture during the microsurgery. The pre-operative and the post-operative corneal curvatures of patients in both groups were measured and the results were compared. The comparison shows that the clinical effect in regard to the corneal curvature is better in the group with the application of a transparent keratoscope. In this group, 63% of the post-operative corneal astigmatism is less than 2D, 91% less than 3D and none more than 4D.
