The Effectiveness and Safety of Dextenza 0.4 mg for the Treatment of Postoperative Inflammation and Pain in Patients After Photorefractive Keratectomy: The RESTORE Trial.

PURPOSE: To determine patient preference and treatment outcomes with an intracanalicular dexamethasone 0.4 mg insert compared to a standard steroid drop regimen in the contralateral eye following bilateral photorefractive keratectomy (PRK). METHODS: In this randomized, prospective, self-controlled, open-label interventional study, one eye received the dexamethasone insert and the second eye received prednisolone acetate 1% taper following bilateral PRK surgery. Postoperative evaluations were performed on day 3, day 4, month 1, and month 3. Phone call surveys were performed on week 2. The Comparison of Ophthalmic Medications for Tolerability questionnaire was used to determine patient preference between postoperative regimens and postoperative pain. Corneal endpoints included time to epithelialization, presence of corneal haze, sodium fluorescein staining, and modified Standardized Patient Evaluation of Eye Dryness (SPEED) scores. Both corrected distance visual acuity (CDVA) and uncorrected distance visual acuity (UDVA) were assessed. RESULTS: Twenty patients participated in the study. At month 3, 70% of patients preferred the dexamethasone insert, 20% preferred prednisolone acetate, and 10% expressed no preference. Patient surveys did not show a difference in postoperative pain between the study group and control group. No statistical difference was shown in time to epithelialization, 90-day CDVA or UDVA, postoperative corneal haze, corneal staining, or modified SPEED scores. CONCLUSIONS: In patients undergoing PRK, there was preference toward a dexamethasone insert in place of topical prednisolone acetate for the postoperative steroid treatment. There were no statistically or clinically significant differences between the two cohorts in regard to healing time or visual outcomes. [J Refract Surg. 2021;37(9):590-594.].

A Randomized Fellow-Eye Clinical Trial to Evaluate Patient Preference for Dexamethasone Intracanalicular Insert or Topical Prednisolone Acetate for Control of Postoperative Symptoms Following Bilateral Femtosecond Laser in Site Keratomileusis (LASIK).

PURPOSE: To determine the preference of patients undergoing bilateral LASIK for either the dexamethasone intracanalicular insert or topical prednisolone acetate for control of postoperative symptoms and ocular surface signs. METHODS: In this randomized clinical trial, one eye was randomized to receive the dexamethasone insert or topical prednisolone acetate 1% four times daily for one week and 2 times daily for a second week; the fellow eye received the alternate therapy. One month postoperatively, patient preference for these two therapies was assessed using an adapted COMTOL questionnaire. Ocular comfort was assessed using the SPEED questionnaire. Corneal staining and uncorrected distance visual acuity (UDVA) were also assessed. RESULTS: Twenty patients participated. At Month 1, 80% of patients preferred the dexamethasone insert, 10% preferred prednisolone acetate, and 10% expressed no preference (p<0.001). SPEED scores measuring ocular comfort/discomfort related to dry eye symptoms were similar between groups (p=0.72), and both the incidence of patient-reported ocular dryness and the corneal staining scores were similar between groups. Both groups attained the same final UDVA. CONCLUSION: Patients undergoing elective bilateral femtosecond LASIK surgery overwhelmingly (by an 8-to-1 margin) preferred the dexamethasone insert to topical prednisolone acetate for postoperative treatment. The insert produced comparable ocular comfort, corneal staining, and visual acuity outcomes to topical prednisolone. The insert is an appropriate means of postoperative symptom control in this quality of life-conscious population.
