The study complied with the tenets of the Declaration of Helsinki and was approved by the Ethics Board of the Beijing Tongren Hospital. Written informed consent was obtained from all patients before surgery. A total of 63 cases (84 eyes) of RP combined with cataract treated in our hospital from January 2014 to October 2019 were collected, including 30 males and 33 females, aged 35-58 years, with an average age of 42.8 years. Phacoemulsification with a 3.0mm clear corneal incision was performed in all the patients.

All the collected cases were RP patients with cataract, no other eye diseases, no history of eye surgery or trauma.
