Initiating the Scleral Lens Fit Prior to CXL

Corneal cross-linking (CXL) is universally accepted in the management of corneal ectasia; however, there are fewer publications on the sequencing or timing of when CXL or scleral lenses should be performed.

5 Key Takeaways

  • 1

    Corneal cross-linking (CXL) is effective for managing corneal ectasia but does not correct corneal irregularities affecting visual acuity.

  • 2

    Scleral lenses can improve vision post-CXL and may be fitted before the procedure if vision is inadequate for daily activities.

  • 3

    A study evaluated scleral lens fittings before CXL, showing no significant changes in corneal measurements pre- and postoperatively.

  • 4

    The findings suggest that initiating scleral lens fittings before CXL can streamline the prescription process and reduce postoperative visits.

  • 5

    Scleral lenses can be safely fitted before CXL and resumed one month after the procedure, supporting optimal vision maintenance.
