Clinical Scorecard: Assessment of Corneal Biomechanical Properties Following SMILE and LASEK in Patients with Moderate to High Myopia and Thin Corneas: A Retrospective Comparative Analysis
At a Glance
Category
Detail
Condition
Moderate to high myopia with thin corneas (CCT ≤ 530 μm)
Key Mechanisms
Evaluation of corneal biomechanical properties post-surgery using metrics like bIOP, SP-A1, IntInv-Rad, DAR 2.0 mm, and ARTh.
Target Population
Patients aged > 18 years with myopia and thin corneas
Care Setting
Ophthalmology clinics performing corneal refractive surgery
Key Highlights
SMILE and LASEK induce fewer biomechanical changes compared to LASIK.
Study focuses on corneas with CCT ≤ 530 μm, a transitional thickness range.
Long-term biomechanical stability is critical for surgical success, evaluated at 2 years post-op.
Guideline-Based Recommendations
Diagnosis
Comprehensive preoperative ophthalmic examination including corneal topography and biomechanics.
Management
Select surgical technique based on corneal characteristics and patient expectations.
Monitoring & Follow-up
Evaluate corneal biomechanical properties at 2 years to assess stability and risk of ectasia.
Risks
Iatrogenic keratectasia is a significant concern in patients with thin corneas.
Patient & Prescribing Data
47 patients (47 eyes) with moderate to high myopia and thin corneas.
SMILE preferred for sufficient corneal thickness; LASEK for thinner corneas and specific occupational needs.
Clinical Best Practices
Utilize shared decision-making for surgical technique selection.
Monitor postoperative healing and biomechanical stability over 2 years.
