Background: Global acclaim has been accorded to the Vision Implantable Collamer Lens, a posterior chamber phakic intraocular lens used to cure extreme myopia. Goals & Aims: of this research is to use Pentacam and specular microscopy to assess the changes to the eye's anterior chamber (AC) and endothelial cell count after the placement of an implanted Collamer lens (ICL) in individuals with wide myopia. Procedures and cases forty eyes were employed in this prospective, non-comparative, non-randomized follow-up research, which also made use of Al-Azhr University's eye care facilities in Assiut. Results: Between preoperative, 30 days after surgery, and 3 months after surgery, there were no discernible differences, 6 months after surgery. Preoperative, 30 days postoperative, three months postoperative, and 6 month postoperative observations all showed a substantial reduction in IOP (mmhg). After ICL implantation, the ACA and CACD are markedly lowered. Conclusion: The ACA and CACD are dramatically decreased after ICL implantation. Those modifications must be taken into consideration when deciding whether a case is eligible for ICL installation. ICL implantation has no impact on pupil size or corneal angles, which may ensure satisfactory vision after surgery.
