Clinical Scorecard: Comparative Analysis of Higher-Order Aberrations Following Toric Implantable Collamer Lens Surgery Versus Implantable Collamer Lens with Limbal Relaxing Incision
At a Glance
Category
Detail
Condition
Moderate Astigmatism
Key Mechanisms
Implantable Collamer Lens (ICL) and Limbal Relaxing Incision (LRI) for astigmatism correction
Target Population
Patients aged 18-38 with myopia and moderate astigmatism (1.00-1.75 D)
Care Setting
Ophthalmic surgical centers
Key Highlights
Both ICL + LRI and TICL groups achieved comparable visual acuity outcomes postoperatively.
Surgically Induced Astigmatism (SIA) decreased in the LRI group but remained stable in the TICL group.
Total corneal wavefront aberrations reduced in the LRI group, while slightly increased in the TICL group.
Guideline-Based Recommendations
Diagnosis
Assess preoperative astigmatism and myopia levels.
Management
Consider ICL combined with LRI for moderate astigmatism correction.
Monitoring & Follow-up
Evaluate visual acuity and corneal aberrations at 1 week, 1 month, and 3 months postoperatively.
Risks
Monitor for lens rotation in TICL and potential increases in higher-order aberrations.
Patient & Prescribing Data
Patients with myopia and moderate astigmatism undergoing ICL surgery.
ICL + LRI may offer a cost-effective alternative to TICL with comparable efficacy.
Clinical Best Practices
Ensure thorough preoperative assessment of astigmatism and myopia.
Utilize experienced surgeons for ICL and LRI procedures.
Follow postoperative care protocols including antibiotic and corticosteroid use.
AI offers meaningful opportunities to improve efficiency in ophthalmic ASC coding and revenue cycle workflows, but accurate reimbursement still depends on structured review and oversight.
