Analgetic Effect of Two Solutions of Intracameral Anesthesia During Cataract Surgery in Patients

Summary

Purpose: The aim of the study was to compare the analgetic effect of two solutions of intracameral anesthesia in patients undergoing cataract surgery and assess the factors influencing the patients' postoperative activities.

Methods: In this prospective, single-blind, randomized study, a group of 62 patients undergoing cataract surgery received Mydrane (Mydrane group) or a combination of 1% solution of lignocaine and 0.025% solution of adrenalin (reference group) as an intraocular anesthetic. The analgetic effect of these two anesthetic methods was evaluated using psychological tools - Visual Analog Scale for Pain (VAS Pain) and Brief Pain Inventory-short form (BPI) on the next day after the surgery.

Conditions

• Cataract
• Analgesia
• Ophthalmological Disorder

Interventions

DRUG

lignocaine

The group of 62 patients undergoing cataract surgery received Mydrane (Mydrane group) or a combination of 1% solution of lignocaine and 0.025% solution of adrenalin (reference group) as an intraocular anesthetic

PROCEDURE

Phacoemulsyfication

Phacoemulsification is a technic of cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye.

PROCEDURE

Intraocular lens implantation

An intraocular lens implant is a synthetic, artificial lens placed inside the eye that replaces the focusing power of a natural lens that is surgically removed, usually as part of cataract surgery.

BEHAVIORAL

Visual Analog Scale for Pain

VAS for Pain is a new tool developed to assess the pain in quantitative terms.

BEHAVIORAL

Brief Pain Inventory-short form

BPI short form is a tool developed to assess the pain in quantitative terms. The BPI allows patients to rate the severity of the pain and the grade to which their pain interferes with common dimensions of feeling and function.

DIAGNOSTIC_TEST

Best corrected visual acuity measurment

Measurement of the best vision correction that can be achieved, such as glasses, as measured on the standard Snellen eye chart. For example, if your uncorrected eyesight is 20/200, but you can see 20/20 with glasses, your BCVA is 20/20.

DIAGNOSTIC_TEST

Slit-lamp biomicroscopy

Slit-lamp biomicroscopy allows study of ocular structures and their relationships.
