ABSTRACT
PURPOSE: To describe a unique method of biometric calculation and surgical technique of phacoemulsification and posterior chamber intraocular lens (PCIOL) implantation with an implantable collamer lens (ICL) in situ; for a high hyperope with post - ICL cataract. OBSERVATIONS: A patient with high hyperopia who underwent bilateral ICL implantation later developed cataract in both eyes. He underwent phacoaspiration of the cataract with ICL in situ and a standard power PCIOL implantation in the left eye. A unique method of PCIOL power calculation was later devised for the right eye by accounting for the residual refractive error of the eye and implanted by a similar surgical technique. CONCLUSION AND IMPORTANCE: Following cataract surgery with the ICL in situ, the patient had a residual refractive error of +3.00D in the left eye however had a minimal residual refractive error in the right eye. A new surgical method of PCIOL implantation after cataract extraction with an ICL in situ as well as the biometric calculation for a PICOL to be implanted with an ICL in situ was devised.
