ABSTRACT

Unlabelled: Purpose. To describe a case of 3 refractive procedures performed in one eye over 2 decades. Methods.

Case report: Results. A 41-year-old patient presented for refractive surgery evaluation. His ocular history includes bilateral radial keratotomy performed 21 years ago for moderate myopia: spherical equivalence of -4.25 D bilaterally. Postoperative uncorrected visual acuity (UCVA) was 20/30; however, over time he developed a hyperopic shift and UCVA decreased to 20/40 in the right eye. Thus, laser-assisted in situ keratomileusis (LASIK) was performed at an outside institution 6.5 years later, and the patient had initial improvement of UCVA to 20/25. Due to a change in refractive error, the patient underwent uneventful astigmatic keratotomy 13 years after LASIK in the right eye, and 1.5 years after surgery best-corrected visual acuity was 20/25 with manifest refraction of -1.00 + 5.50 × 134°.  Conclusion. We report the outcomes and natural refractive progression in a patient who underwent three corneal refractive procedures over two decades. This case underlines the difficulties of long-term management of post-RK hyperopia and astigmatism.

Corneal Topography. Progression of corneal topography measured in patient's right eye: (a) preoperative topography (before radial keratotomy [RK]), (b) postoperative month 1 after RK, (c) postoperative month 5 after LASIK, (d) postoperative year 6 after LASIK, (e) postoperative month 4 after astigmatic keratotomy (AK), and (f) postoperative year 1.5 after AK.

Mentions: A 41-year-old Hispanic man who wore soft contact lenses for 15 years presented to Bascom Palmer Eye Institute for refractive surgery evaluation 21 years ago. In the right eye, uncorrected visual acuity (UCVA) was 6/200 and manifest refraction (MR) was −4.5 sphere with corrected distance visual acuity (BCVA) 20/20. Preoperative topography showed a low amount of with-the-rule astigmatism (corneal cylinder (CC) = 0.40 D; Figure 1(a)). In the left eye, initial UCVA was 7/200 and MR was −4.5 sphere with BCVA 20/20. Preoperative topography showed a low amount of with-the-rule astigmatism (CC = 0.73 D). To correct this patient's refractive error, RK was performed bilaterally.
