  • Abstract
  • Look Inside

 Cataract surgery was planned for the left eye of a 67-year-old woman. She had had hyperopia of about+10.5 diopters(D). She had received laser in situ keratomileusis(LASIK)21months before. After temporary improvement of hyperopia by about 5D,her left eye had hyperopia of+9D before cataract surgery. We compared the following 3methods in determining the power of intraocular lens(IOL). Use of SRK/T formula using keratometric data obtained by clinical history method. Use of ray-tracing analysis of anterior and posterior corneal power as measured by Orbscan(R). Use of same data processed by SRK/T formula. We performed cataract surgery using the first method. She obtained visual acuity of 0.8 by an equivalent spherical correction of-1.25D.
