Systematic evaluation of wavefront-guided outcomes.

Abstract

PURPOSE: To present a format for reporting outcomes of aberrometer-guided refractive procedures. SETTING: SurgiVision Consultants, Inc., Scottsdale, Arizona, and Food and Drug Administration, Center for Devices and Radiological Health, Rockland, Maryland, USA. METHODS: Reports of standard refractive and visual outcomes (uncorrected visual acuity, manifest refractive spherical equivalent, best spectacle-corrected visual acuity) should be provided for any refractive surgery report. Comparison of postoperative uncorrected visual acuity to preoperative best spectacle-corrected visual acuity should be included. Aberration reports should convert 2nd-order terms to refractions (measured in diopters) and use standard refractive reporting methods. Changes in coma, spherical aberration, and root-mean-square changes should be described using statistical methods for aggregate data. Underlying statistics should be reported. RESULTS: Aberration changes are well described by the mean error of the attempted versus achieved outcomes, comparison of the mean changes, and stability over time. Ancillary plots include histogram representation of the postoperative scores. Additional reports of visual function should be included, as appropriate. CONCLUSION: Use of standardized tables and graphs permits qualitative and quantitative comparison of outcomes of refractive treatment with wavefront-guided lasers. Modifications of the recommended formats can be expected over time.

Rapid growth of pterygium after photorefractive keratectomy.

BACKGROUND: A pterygium is a fibrovascular overgrowth of degenerative conjunctiva over the limbus onto the cornea. The risk factors for pterygium development include exposure to ultraviolet (UV) light, dust, wind, heat, dryness, and smoke. As far as we are aware, rapid growth of pterygium secondary to photorefractive keratectomy (PRK) has not been reported previously. CASE REPORT: A 49-year-old man presented with blurring vision in the left eye. The patient had undergone PRK in both eyes at another surgical center 11 months prior. Examination found a pterygium extending 3 mm over the corneal midline and covering 60% to 70% of the cornea. Information regarding the extent of the pterygium in the left eye was limited; however, preoperative drawings showed a moderate extension of about a 3-mm encroachment into the nasal cornea. However, the patient stated that the 2 sides "looked similar" before PRK and that the right side remained "pretty small" after surgery. CONCLUSION: Several growth factors have been detected in the cornea during the recovery from PRK surgery. Those growth factors might have the potential to exacerbate the growth of a pterygium. Further studies are needed to draw any conclusion regarding the consequence of PRK surgery on the growth of a pterygium so patients can be better informed and managed. As eye care providers, we should be aware of the potential that rapid growth of a pterygium may occur after PRK.
