Incisions used for orbital floor exploration continues to remain a topic of controversy. Historically, 3 incisions have been used for orbital floor repair: transconjunctival, subciliary, and subtarsal. Past studies have attempted to stratify the superiority of one incision over the others. Insufficient level of evidence and inconsistent methodology have lead to inconclusive data. Our authors performed a systematic review of literature to assess the quality of evidence in literature and recommend guidelines for incisions for repairing orbital fractures. Thirty-one articles were identified, comprising a total of 4688 incisions. Technique along with individual benefits and complication profiles for each incision is reviewed. Objectivity and follow-up time intervals are necessary parameters for evaluating incisions for orbital floor exploration to further define guidelines.

This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .

Pentacam and IOLMaster agree well for corneal power but less so for cylinder and axis of astigmatism and thus cannot be used interchangeably.
