To evaluate the efficacy and complications of a new type of minimally invasive femtosecond laser assisted-cataract surgery (FLACS) combined with pars plana vitrectomy (PPV) with two-step anesthesia in the treatment of various common fundus diseases such as rhegmatogenous retinal detachment (RRD), epiretinal membrane (ERM), macular hole (MH), and vitreous opacity, complicated with cataract. It is mainly aimed at the following kinds of common fundus diseases with cataract performing PPV and cataract removal combined with monofocal or premium intraocular lens (IOL) implantation： RRD complicated with cataract: FLACS +PPV + IOL+air; ERM complicated with cataract: FLACS +PPV+IOL + epiretinal membrane peeling + Ozurdex; MH complicated with cataract: FLACS + PPV+ IOL + internal limiting membrane peeling + air; Vitreous opacity with cataract: FLACS + PPV+ IOL.
Based on the progress of cataract surgery, intraocular lens development, vitreoretinal surgery and anesthesia technology in recent years, the purpose of this study is to develop a new type of more accurate and minimally invasive combined surgery for cataract and fundus diseases, and to evaluate the advantages and value of the surgery as well as related complications, so as to minimize the surgical trauma and obtain faster visual function recovery and better patient comfort. To provide new solutions for the growing demand of eye health care.
