2021 Survey of Keratoplasty Postoperative Steroid Management

The aim of the study is to investigate US-based ophthalmologists' preferred corneal transplant techniques and postoperative steroid regimen.

Ophthalmologists attending the 2021 Cornea and Eye Banking Forum and/or Cornea Subspecialty Day were surveyed in person.

Ninety-two ophthalmologists with a median of 13 years (range of 1-35; mean of 14.5; ±9.05 mean ± SD) of experience as attending clinicians were surveyed. One hundred percent of the surgeons performed penetrating keratoplasty, which was followed by 96.7% for Descemet stripping endothelial keratoplasty, 90.2% for Descemet membrane endothelial keratoplasty, and 72.8% for deep anterior lamellar keratoplasty. Prednisolone 1% for postoperative care was the preferred choice across all surveyed keratoplasty techniques and postsurgery time intervals. All surgeons reported steroid administration frequency of 4 times a day in the first month and once a day after 12 months postkeratoplasty. To manage ocular hypertension after corneal transplantation, the leading approach was adding a glaucoma medication (44.6%), and beta-adrenergic antagonists were ranked as the most preferred choice by 59 (66.3%) of the respondents. For graft rejection after corneal transplantation, topical steroids (79.8%) were the initial treatment of choice with hourly administration being the most common frequency prescribed (87.4%). Most surgeons either agreed or strongly agreed (78.4%) that a randomized clinical trial evaluating the safety and efficacy of different steroid regimens after corneal transplantation would influence their clinical decision making.

Prednisolone remains the predominantly used steroid across different keratoplasties. Steroid regimens are similar for non-high-risk penetrating keratoplasty, Descemet membrane endothelial keratoplasty, Descemet stripping endothelial keratoplasty, and deep anterior lamellar keratoplasty. To treat graft rejection, surgeons tend to initially add a glaucoma medication than to reduce the potency or frequency of the steroid.
