Summary

Compare postoperative Subjective and objective visual quality and economic efficiency of different Intraocular Lens(IOLs) implantation designed for the correction of presbyopia.

Detailed description

Compare postoperative Subjective and objective visual quality and economic efficiency of different Intraocular Lens Implantation designed for the correction of presbyopia.The subjects will undergo bilateral uneventful phacoemulsification and implantation of IOL.The subjects will be divided into several groups according to the type of the IOLs，including monofocal IOL group,monovision designed group ，bifocal IOL group, mix bifocal IOL group，trifocal IOL group，Exteded Depth of Focus(EDOF) IOL group and blend vision group. Compare the Subjective and objective visual quality and economic efficiency among these groups at 3 months postoperatively.

Conditions

• Presbyopia
• Cataract Senile

Interventions

Type	Name	Description
DEVICE	bifocal IOL	The patients will undergo bilateral phacoemulsification and bifocal IOLs implantation.
DEVICE	mix bifocal IOL	The patients will undergo phacoemulsification and mix different bifocal IOLs implantation bilaterally.
DEVICE	trifocal IOL	The patients will undergo bilateral phacoemulsification and trifocal IOLs implantation.
DEVICE	EDOF IOL	The patients will undergo bilateral phacoemulsification and EDOF IOLs implantation.
DEVICE	different IOLs	The patients will undergo phacoemulsification and different IOLs implantation bilaterally.
DEVICE	monofocal IOL	The patients will undergo bilateral phacoemulsification and monofocal IOLs implantation with monovision designed.
DEVICE	monofocal IOL	The patients will undergo bilateral phacoemulsification and monofocal IOLs implantation with emmetropia designed.
