Background:
The Implantable Collamer Lens (ICL) has gained recognition in refractive surgery for its stability and ability to achieve reversible refractive outcomes.
Aim:
Our study seeks to assess the safety and efficacy of the ICL with a central hole for vision correction procedures within the Lebanese population. Through this investigation, we aim to enhance our understanding of ICLs and their applicability in refractive surgeries, thus contributing valuable insights to the existing body of knowledge in this field.
Methods:
We conducted a prospective cohort study spanning two years. The study included 116 eyes of 58 patients who underwent surgical implantation of the Visian ICL V4c model. The participants were patients aged between 20 and 45 years, with a stable history of refraction and a medical history of myopia ranging from −2.00 to −20.0 diopters (D) and cylinder up to 3 D. Refractive outcomes, intraocular pressure, and corneal endothelial cell were evaluated one year and two years post operatively.
Results:
During the two years of follow-up, we observed a significant decrease in the UDVA (uncorrected distance visual acuity), CDVA (corrected distance visual acuity), SPH (sphere), CYL (cylinder), and SPH EQ (sphere equivalent). However, there was no variation in the IOP (intraocular pressure) recorded, and the ECC (endothelial cell count) remained stable during the first year following the surgery, but decreased slightly during the second year. Furthermore, we found that an increase in the anterior chamber depth value is associated with a decrease in ECC loss. Importantly, no complications were noted during the two years of postoperative follow-up.
Conclusion:
The implantation of the ICL is a safe and effective treatment for myopic astigmatism, improving visual acuity without complications.
