About this study
Official title: Identification of Clinical, Biometrical and Operatory Factors Related to Pain During Cataract Surgery / RECHMPL20_0210
Adults who undergo cataract surgery will be questioned after surgery about the eventual pain they experienced, about their health history, personal treatment. If they accept to be included in the study we'll record different parameters related to the surgery: type of anesthesia, duration of surgery, machines used, unexpected events, particularities noticed by the surgeon, etc.
There will be no unusual intervention, everything will be run exactly as if there was no study. No additional consultation needed.
Read the detailed description
Adults who undergo cataract surgery, excepting under general anesthesia, will be asked to rate a Visual Analog Scale grading the pain they experienced, about their health history, personal treatment. If they accept to be included in the study we'll record different parameters related to the surgery: Visual analog scale of pain according to the surgeon (before recording the patient), type of anesthesia, duration of surgery, machines used, time of ultrasound used for phakoemulsification, preoperoative visual acuity and intraocular pressure, biometry, iris color, preoperative donesis, preoperative capsular pseudoexfolliation, unexpected events, particularities noticed by the surgeon as Floppy iris syndrome, Lens-iris diaphragm retropulsion syndrome There will be no unusual intervention, everything will be run exactly as if there was no study. No additional consultation needed.
