April 12, 2011 updated by: Grupo de Estudos em Oftalmologia Clínica e Cirúrgica

Study of Endothelial Cell Density of Corneas Undergoing Phacoemulsification Surgery Using Balanced Salt Solution (BSS ®) Versus Glucose-bicarbonate-Ringer Lactate as Irrigating Solution: a Randomized Clinical Trial.

This is a study aimed at evaluating the effectiveness and impact of two intraocular irrigating solution (BSS ® versus glucose-bicarbonate-Ringer Lactate - GBRL) on the health of the cornea after cataract surgery by phacoemulsification.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Intervention / Treatment

Active Comparator: Balanced Salt Solution (BSS®)
Subjects who received Balanced Salt Solution.
Procedure: Phacoemulsification cataract surgery

A group received BSS ® (ALCON LABORATORIES, INC.) and another group received glucose-bicarbonate-Ringer Lactate (GBRL) [500 cc. Ringer Lactate (GLICOLABOR, Pharmaceutical LTD.) enriched with 1.5 ml of glucose in water (25%) and 08 ml of sodium bicarbonate (8.4%)] as a solution for irrigation during surgery.

All surgeries were performed by single surgeon (HON), using the standard surgical technique quick-chop. Immediately before surgery, solutions for irrigation [BSS ® (ALCON LABORATORIES, INC..) and glucose-bicarbonate-Ringer Lactate (GBRL)] were brought to the operating table in a temperature of 22 degrees Celsius. The microcoaxial Phacoemulsification was performed under a phaco Legacy Series 20000 (ALCON LABORATORIES, INC..).

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
