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.

Purpose To evaluate the clinical outcomes with optometrist pre-surgical insertion of dexamethasone ophthalmic insert 0.4mg in the clinical office setting in patients undergoing same-day cataract surgery compared to standard of care steroid therapy. Methods In this prospective, contralateral eye trial, one eye received a dexamethasone ophthalmic insert 0.4mg and the other received topical prednisolone acetate 1% four times per day for one week, then three times per day for one week, then two times per day for one week, and then one time per day for one week. At one day, seven days, and four weeks postoperatively mean anterior chamber cell score and mean anterior chamber flare score was assessed by Slit Lamp Biomicroscopy and pain score was assessed by Visual Analog Scale from 0–10. Incidence of increased intraocular pressure and cystoid macular edema were also assessed. Results Thirty patients (60 eyes) participated. At one day postoperative there was no significant difference in mean anterior chamber cell score (p= 0.70) or pain score (p= 0.92). There was no anterior chamber cell flare observed in the study or control group. Of the 30 patients, 29 expressed a preference for dexamethasone inserts compared to topical prednisolone acetate. One patient in the study group had elevated intraocular pressure that resolved and there was no cystoid macular edema measured. Conclusion In patients undergoing routine cataract surgery, there was an overwhelming preference for a dexamethasone insert compared to topical steroid drops. The dexamethasone insert produced similar ocular comfort and inflammation prevention compared to prednisolone acetate eyedrops. Dexamethasone inserts are a safe and effective treatment option for reducing pain and inflammation when inserted by an optometrist prior to routine cataract surgery.

To create a defocus curve of emerging presbyopic patients of various age groups. Setting: Single site private practice in Sioux Falls, South Dakota. Design: This was a non-randomized, prospective study. All subjects were enrolled from healthy volunteers. Methods: Subjects aged 37-9, 40-42, 43-45 and 46-48 that have 20/20 best-corrected distance visual acuity (BCDVA) were included. Binocular visual acuity at different defocus steps ranging from +0.5 D to −3 D was measured in each age group. Defocus curves were generated from the mean logMAR visual acuities at each defocus step, by age group. Results: Of the 60 subjects, 23.3% of subjects were between the ages of 37-39, 26.7% were between the ages of 40-42, 25% of subjects were between ages 43-45, and 25% were between the ages of 46-48. Visual acuity significantly decreased from plano to −3 D defocus steps in all groups (p < 0.0002, p = 0, p = 0 and p = 0). The 46-48-year-old group had worse visual acuity compared to the other three groups from the −1.0 to −2.0 D defocus steps (p = 0.037, p = 0.022 and 0.017, respectively). Starting at a near point of 40cm, the 37-39 group had the best logMAR vision and the 46-48 group had the worst vision (p = 0.001). Conclusion:The defocus curves of emerging presbyopic individuals demonstrate a decreasing visual acuity at near defocus steps that decreases with age. Defocus curves at different age ranges can help doctors explain various presbyopia treatment options in terms of near point capabilities at various ages.
