“plus LRs” used for large angles with BMRc
- *lower by 1 mm when resecting laterals after BMRc of 6 or more
- BMRc = Bilateral medial rectus recessions
- plus LRs = Lateral rectus resection used with BMRc
- BLRs = Bilateral lateral rectus resections
- MRc = Medial rectus recession
- LRs = Lateral rectus resection
