Completed
Conditions
Phacoemulsification
Registration Number
NCT03031652
Lead Sponsor
Kyungpook National University Hospital
Brief Summary

Charts of 142 patients who underwent standard phacoemulsification under topical anesthesia between March and August 2016 were reviewed. The pain during phacoemulsification and 1 h after surgery was assessed and compared using a visual analog scale.

Detailed Description

Patients scheduled for elective phacoemulsification and intraocular lens implantation with the Infiniti Vision System (Alcon, Fort Worth, USA) were included. All operations were performed in Kyungpook National University Hospital by the same surgeon between March and August 2016.

Primary Outcome Measures
NameTimeMethod
Pain score assessed with Visual Analogue Scale (VAS)1 hour after the end of surgery

Visual Analogue Scale (VAS) is a measurement instrument that tries to measure a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured.

A third person assessed subjective pain using a pain visual analog scale ranging from 0 (no pain) to 10 (worst pain imaginable) after surgery.
