Prospective Clinical Study of Unilateral or Bilateral Implantation of Intraocular Lens in Cataract Patients

2020-02-16 17:40:49 | BioPortfolio


This is to evaluate the satisfaction of patient and postoperative functional vision of unilateral or bilateral Implantation of intraocular lens(IOLs) in cataract patients.


The subjects will undergo uneventful phacoemulsification and implantation of IOL.

The subjects will be divided into two groups . The unilateral cataract patients in the Group 1 will undergo unilateral surgery, and the bilateral cataract patients in the Group 2 will undergo bilateral surgery. IOL may be monofocal,bifocal ,or trifocal,according to the patients preference and the eyes condition. In each group, the subjects will be divided into three subgroups according to the type of the IOLs.Compare binocular functional vision and the satisfaction of patient between the two groups at postoperative 3 months.Compare binocular functional vision and the satisfaction of patient with different IOLs among the subgroups.
