No Drop Post-Op Cataract Surgery

This study evaluates the effect of Intraocular Phenylephrine/Ketorolac Infusion on Retinal Thickness and Macular Edema in Cataract Surgery. Participants will receive infusions of Phenylephrine/Ketorolac during surgery instead of receiving topical NSAID drops pre and post operatively.

About this study

Topical NSAIDs have been known to reduce post-operative macular edema, inflammation and pain in patients undergoing cataract surgery. Routine cataract surgery without the protection of topical NSAIDs results in an increase of the number of patients with macular edema and macular thickening.

Omidria (phenylephrine and ketorolac injection 1%/0.3%) infusion is used in patients during cataract surgery to decrease post-operative pain and inflammation. It is also indicated to maintain pupil dilation during cataract surgery.

This study will evaluate whether treating patients with Omidria during cataract surgery will control post-operative pain and inflammation as well as reduce or eliminate macular edema without the use of adjunctive topical NSAIDs.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adults age 55-90 years with visual significant cataracts in one or both eyes.
  • Healthy individuals able to tolerate outpatient cataract surgery under local anesthesia via either phacoemulsification and/or femtosecond assisted cataract surgery. Well-controlled diabetes, hypertension will be included.
  • Females of childbearing potential must agree to use a reliable method of birth control while participating in this study. Reliable methods of birth control are: abstinence, oral contraceptives, intrauterine device (IUD), DepoProvera, tubal ligation or vasectomy of the partner (with confirmed negative sperm counts) in monogamous relationship (same partner). An acceptable, although less reliable, method involves the careful use of condoms and spermicidal foam or gel and/or cervical cap or sponge. A pregnancy test is required at least 10 days from the last normal menstrual period, if the patient is a sexually active female of childbearing potential.

Exclusion criteria

  • Allergy to Phenylephrine or NSAIDs.
  • Inability to sit steady and upright for the Optical Coherence Tomography (OCT).
  • Complications during surgery, including posterior capsular rupture, vitreous loss, zonular dialysis, or iris trauma.
  • Macular thickness above 300 microns at baseline
  • Currently taking a prostaglandin analogue
  • Presence of an epiretinal membrane on the preoperative OCT.
  • Retained lens fragment post-operatively.
  • Inability to return for follow appointments
  • Female patients who are pregnant, lactating or planning to become pregnant during the course of treatment.

Treatment and study plan

Omidria

Drug

Phenylephrine and Ketorolac infusion of 1%/0.3% during cataract surgery.

Primary outcomes

  1. Best Corrected Visual Acuity (BCVA) (Pre-op)

    Time frame: Baseline

    Best vision will be tested with lens correction using Snellen Charts.

  2. Best Corrected Visual Acuity (BCVA) (Week 2)

    Time frame: 2 weeks

    Best vision will be tested with lens correction using Snellen Charts to determine if improvements have been made post-operatively.

  3. Best Corrected Visual Acuity (BCVA) (Week 6)

    Time frame: 6 weeks

    Best distance vision will be measured clinically to determine if improvements have been made post-operatively.

  4. Number of Participants That Develop Presence of Cystoid Macular Edema (CME)

    Time frame: 2 weeks

    The number of participants that develop CME will be recorded to evaluate if Omidria is sufficient in controlling CME. The presence of CME will be determined clinically.

  5. Change From Baseline in Macular Thickness Measurement - Number in Microns

    Time frame: Baseline and week 6

    The thickness of the macula will be measured pre and post operatively using ocular imaging to determine if Omidria is sufficient in controlling thickening post-operatively - measured in number of Microns

  6. Number of Participants Needing NSAID Post-operatively

    Time frame: Post-op weeks 1 through 6

    Need for topical NSAID (rescue med) will be assessed at all post-op visits. If at any time the patient shows signs of cystoid macular edema, inflammation or pain, NSAIDs will be administered. The number of patients needing NSAID post-operatively will help determine if NSAIDS are needed.

  7. Change in Anterior Chamber Cells From Baseline Measurement

    Time frame: Week 6

    Anterior chamber cells will be assessed through a dilated eye exam to determine if NSAIDS are needed post-operatively in addition to Omidria during surgery.

    Range and meaning (if score/scale): 0-2 0 = no cell

    • = 10-20 cells
    • = greater than 20 cells
