Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Arm 1; PRO-149
Viscoelastic substance PRO-149 (sodium hyaluronate 3%) in pre-filled syringe to be applied in the ocular anterior chamber during phacoemulsification surgery in an amount sufficient to form the desired intraocular space and allow the technical maneuvers required for the procedure.
|
During intraocular surgery phacoemulsification and intraocular lens implantation, patients with age-related cataract will be exposed to injection of viscoelastic device in the anterior chamber, allowing the procedure to take place.

Active Comparator: Arm 2; Healon® EndoCoat
Viscoelastic substance Healon® EndoCoat (sodium hyaluronate 3%) in pre-filled syringe to be applied in the ocular anterior chamber during phacoemulsification surgery in an amount sufficient to form the desired intraocular space and allow the technical maneuvers required for the procedure.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Change in corneal endothelial cell count
Time Frame: Days: -15 (±2) (eligibility visit), and 29 (±2) (final visit)
|
By means of specular microscopy, endothelial cell count will take place.
Density expressed in cells/mm2 will be recorded.
Normal density varies according to age, but an average of 1500 - 3500 cells/mm2 (age 40 to 90) has been described.

Days: -15 (±2) (eligibility visit), and 29 (±2) (final visit)
|
Change in intraocular Pressure (IOP)
Time Frame: Days: -15 (±2) (eligibility visit), 1 (first safety evaluation visit), 8 (±2) (second safety evaluation visit), and 29 (±2) (final visit)
|
Measured through Goldman tonometer in milligrams of mercury (mmHg).
After instillation of topical anesthetic (tetracaine 0.5%) and fluorescein stain, IOP is evaluated twice to obtain an average to be recorded.
Normal values are considered between 10 and 21 mmHg.
