  • Planned multiple procedures during cataract surgery (for example, trabeculectomy, keratotomies, etc)
  • Previous history of ocular trauma in the eye to withstand surgery (including surgical procedures)
  • Having one functional eye.
  • Having participated in clinical trials within 30 days prior to signing this study's informed consent form.
  • Having participated previously in this study.
  • Previous history of drug addiction within the last 2 years prior to signing this study's informed consent form.

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.
Other Names:
  • Healon® EndoCoat
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.
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.

Primary Outcome Measures

Outcome Measure
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)

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.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Trans-surgical evaluation
Time Frame: Days: 0 (surgery)
During the phacoemulsification and intraocular lens implantation, the surgeon will evaluate the performance of the viscoelastic substance used during the procedure trough a questionnaire that will inquire on the following: Capability to maintain a formed anterior chamber during continuous circular capsulorhexis and intraocular lens implantation, retention during phacoemulsification, user-friendliness, ergonomics, ease of use during capsulorhexis, transparency during surgery and ease of use during extraction.
