Summary
New guidelines offer evidence-based recommendations for keratorefractive lenticule extraction (KLEx) procedures. These guidelines aim to improve patient outcomes and minimize complications in refractive surgery.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Keratorefractive lenticule extraction (KLEx) involves removing corneal tissue via small incisions, avoiding flaps.
- KLEx has rapidly gained popularity for refractive correction.
- No established clinical practice guidelines previously existed for KLEx.
Purpose of the Study:
- To develop evidence-based clinical practice guidelines for keratorefractive lenticule extraction (KLEx).
Main Methods:
- Guidelines developed using WHO methodology, AGREE II, and PRIME statement.
- Evidence synthesized from 8 literature databases and 5 guideline databases.
- Recommendations formulated via Delphi consensus of 44 global experts.
Main Results:
- 38 recommendations developed for KLEx, covering screening, planning, surgery, and complications.
- 29 (76%) recommendations were strong, focusing on effective refractive correction and complication management.
- Corneal biomechanics and research gaps for enhancing safety were identified.
Conclusions:
- Evidence-based guidelines for KLEx are now available for clinical practice.
- Guidelines address preoperative screening, surgical planning, and complication management.
- Implementation is expected to minimize complications and enhance outcomes in refractive surgery.
