NCT03031652

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.

Outcome Measures

Primary Outcomes (1)

  • Pain score assessed with Visual Analogue Scale (VAS)

    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.

    1 hour after the end of surgery

Study Arms (1)

Enrolled group

Patients who had senile cataract and underwent phacoemulsification with topical anesthesia.

Device: Phacoemulsification

Interventions

The device device used to provide and perform small profile entry for cataract extraction with or without option of insertion of a specified intraocular lens implant

Also known as: INFINITI® Vision System
Enrolled group

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients who had senile cataract and needed to receive cataract surgery (phacoemulsification) under topical anesthesia were included.

You may qualify if:

  • Patients underwent phacoemulsification with topical anesthesia

You may not qualify if:

  • Patients who needed general anesthesia or were taking medications capable of affecting perceived pain
  • Patients who had traumatic cataract and/or conditions likely to require vitrectomy and trans-scleral fixation of posterior chamber intraocular lens
