Plain English Summary
Background and study aims
The aim of this study is to detect the changes in pupil size following cataract surgery.
Who can participate?
Adults aged 48 to 81 and undergoing cataract surgery.
What does the study involve?
All patients will receive the same type of intraocular lens. Measurements will be made five minutes after the operation and then one month after the operation.
What are the possible benefits and risks of participating?
The benefit is better visual acuity after the operation. The risk is complication after standard cataract surgery.
Where is the study run from?
Uskudar University, Istambul (Turkey).

Study information
Scientific title
Changes in pupil size following phacoemulsification surgery: a prospective cohort study
Acronym
Study hypothesis
The pupil size is important in appropriate cases in whom the combination with phacoemulsification and multifocal intra occular lenses (IOL) implantation would be performed. This is because postoperative visual disturbances may be directly related to the pupil size. Therefore, pupil size assessment of the patients who are to undergo implantation of a multifocal lens is important.
