Failure of Primary Posterior Continuous Curvilinear Capsulorhexis? A Case Report

The aim of the study is to present the possible development of proliferative secondary cataracts in the unique case of a patient having undergone premium cataract surgery with preventive primary posterior continuous curvilinear capsulorhexis (PCCC). Due to the negative effect on visual functions, it was decided to treat the patient with an Nd:YAG laser, which was successful with minimal energy but resulted in damage to the anterior hyaloid membrane. Case report In 2020, a 65-year-old man underwent uncomplicated cataract surgery in both eyes at our clinic bilaterally with primary PCCC with implantation of a tension ring and an artificial intraocular lens into the capsule. In February 2023, on the recommendation of the area ophthalmologist, he was examined at our outpatient clinic due to a decrease of visual acuity in the right eye. Blurred vision predominated. A diagnosis of proliferative form of secondary cataract was confirmed and documented using a photo of the anterior segment in retroillumination and anterior segment OCT (Optovue, Avanti RTVue XR). The patient was indicated for Nd:YAG laser disruption by proliferation in the PCCC space in the right eye. The return of visual acuity to its original state confirmed the correct diagnosis. The literature review and discussion summarize the current issue of secondary cataracts and the use of primary PCCC. Conclusion: Secondary cataract is the main long-term complication of modern cataract surgery. One of the possible solutions is the preventive implementation of a simple PCCC, which may be accompanied by isolated failure.
