This case series seeks to evaluate the vision and refractive outcomes of patients who sought Raindrop corneal inlay removal with or without concomitant LASIK treatment.
This study utilizes a case series design and retrospective data review of electronic medical records from a private ophthalmology clinic in Boston, MA. 20 patients who had a Raindrop inlay placed and subsequently removed were identified. To be included in the study, patient records must include vision and refraction measurements from 1) before Raindrop inlay placement, 2) before Raindrop inlay removal, and 3) at least 1 month after Raindrop inlay removal. 14 patients with the necessary records were included in the study*. Of these 14 patients, 7 had Raindrop inlays removed and the remaining 7 had Raindrop inlays removed with concomitant LASIK treatment. (*NOTE: At time of 10/20/19 deadline)
13 out of the 14 total patients had a best corrected distance vision of 20/20 or better prior to inlay placement. This study found that 9 out of these 14 patients had experienced a loss of at least 1 line of best corrected distance vision by the time of inlay removal. Inlay removal was performed at a mean of 494 days, or approximately 16 months, after placement. After inlay removal, 6 out of the 9 patients that sustained a loss of 1 or more lines of best corrected distance vision experienced an improvement in this vision. In patients receiving LASIK at or after time of inlay removal, we found the refractive outcome was close to target in most cases.
Best corrected distance vision improves with corneal inlay removal and simultaneous LASIK is successful in achieving monovision as an alternative treatment for presbyopia.
