ABSTRACT
OBJECTIVES: To investigate the effectiveness of presbyopia correction using multifocal soft contact lenses (MF SCLs) for pseudophakic subjects with monofocal intraocular lenses (IOLs). METHODS: In 11 subjects, after monofocal IOL implantation, disposable MF SCLs (Dailies Total 1 Multifocal, Alcon) were daily used for 3 months. Binocular visual acuity between 0.3 and 5 m was measured using an all-distance vision tester (AS-15, Kowa) at 1 and 3 months and compared before and during MF SCL wear. Binocular contrast sensitivity testing was conducted under mesopic and photopic illuminations at 1 month. RESULTS: The mean manifest refraction spherical equivalent before MF SCL wear was -0.36 D. The add powers of used MF SCLs were +1.25, +2.00, and +2.50 D in 1, 16, and 5 eyes, respectively. The mean binocular visual acuities during MF SCL wear were 20/20 or better between 0.5 and 5 m and significantly improved at 0.7 m or less (P<0.025). There was no change in the mesopic contrast sensitivity, whereas the photopic contrast sensitivity at 18 cycles per degree was degraded during MF SCL wear. CONCLUSIONS: The use of MF SCL was effective for presbyopia correction in pseudophakic subjects with monofocal IOL, and favorable binocular vision would be obtained in a range from distance to intermediate.

PURPOSE: To examine the effects of topical steroid instillation on central corneal thickness in eyes with bullous keratopathy (BK). STUDY DESIGN: Retrospective case series METHODS: Consecutive patients with BK who did not wish to receive corneal transplantation and were treated with 0.1% betamethasone eyedrops were included. Patients with BK treated with 5% sodium chloride (hypertonic saline) eyedrops served as controls. Central corneal thickness (CCT), best-corrected visual acuity (BCVA), intraocular pressure (IOP), BK etiology, and clinical courses from medical records were retrospectively reviewed. We compared the two groups for differences in CCT, BCVA and IOP before treatment and 2 weeks, 1 month, and 3 months after treatment. RESULTS: Eighteen eyes of 18 patients who were treated with betamethasone and 18 eyes of 18 patients who were treated with hypertonic saline were included. There was no significant difference in CCT between the two groups before treatment. The reduction of CCT in the betamethasone group was significantly larger than in the hypertonic saline group at 2 weeks (p = 0.002), 1 month (p = 0.02), and 3 months (p = 0.001) after treatment. Complications such as infectious keratitis and IOP rise did not occur during the observation period. CONCLUSIONS: Topical steroid instillation reduced central corneal thickness in eyes with BK.
