Purpose was to observe the changes of the posterior vitreous attachment after uncomplicated phacoemulsification.
Setting/Venue Today, phacoemulsification is a safe and fast procedure in cataract surgery, which can quickly restore vision in patients with cataracts. However, the physical phenomena used in this technology have some effects on tissues of the eye. Changes in the vitreoretinal interface after phacoemulsification are an interesting subject of study.
Methods. In this retrospective study records of 84 patients aged 67.4±6.2 with senile cataract (lens opacity of grade II according to the Lens Opacities Classification System) were analyzed. Patients were divided into 2 groups according to the position of the posterior hyaloid membrane: 28 eyes were with full attached of the posterior vitreous (non-PVD group) and 56 eyes with partial posterior vitreous detachment (PPVD group) without traction. Patients with any kind of peripheral vitreoretinal degeneration with or without laser coagulation were exclude from analyses. All patients underwent uncomplicated phacoemulsification and in-the-bag intraocular lens implantation surgery. OCT was performed to all patients preoperatively and postoperatively on the 1st day, the 1st, the 4th week, and the 12th week.
Results. In the non-PVD group complete PVD was observed in 1 eye (3.6 %) one day after the operation, in 2 eyes (7.1 %) 1 week, in 4 eyes (14.3 %) 4 weeks and remained the same 12 weeks after the phacoemulsification. Partial PVD was detected in 3 eyes (10.7) one week after the surgery, in 4 eyes (14.3 %) 4 weeks, in 6 eyes (21.4 %) 12 weeks after the operation. In the PPVD group complete PVD was observed in 2 eyes (3.6 %) in 1 week after phacoemulsification, 3 eyes (5.4 %) in 4 weeks and remained the same 12 weeks after the phacoemulsification. There were no cases of postoperative retinal detachment during all period of observation.
Conclusions. This study shows a greater tendency for the appearance or progression of PVD after uncomplicated phacoemulsification of cataract with implantation of a posterior chamber IOL which does not seem to lead to the development of retinal detachment among patients with unchanged periphery of the retina.
