Interesting Patient Cases

This patient had a prescription of Plano in the left eye while the right eye prescription was +0.50-1.25x165. His right eye is now Plano-0.25x165. The upper topography is the right eye prior to Orthokeratology, the lower topography is post-Orthokeratology treatment.

This patient was OD -3.50 - 1.25 x 115 20/20-, OS -5.00 - 1.00 x 085 20/20. Two years later the following information was obtained. These topography maps are standard maps. The right eye refracted -3.50 - 8.00 x 069 and corrected to 20/25-. The left eye is -6.25 - 0.25 x 105 with 20/20 acuity. The patient was now fit into a custom back surface toric soft lens on the right eye that gives 20/25+1. The left eye is in a steep spherical soft lens with 20/20 acuity.

This patient has a distance prescription of OD = Plano -0.25DC, OS = +0.25 - 0.75DC with the need for a near add of +1.75. A target of +1.50D on the left eye is the goal of this case while leaving the right eye alone to achieve a monovision effect. The upper topography map is pre-lens wear and the lower map is one month later. LW wears the lens approximately 2 hours per day and the reading vision is clear and stable for the remainder of the day.
