Trial Outcomes & Findings for Wavefront-guided LASIK for Monovision Treatment of Myopic Subjects With Presbyopia (NCT NCT04075591)

Wavefront-guided LASIK for Monovision Treatment of Myopic Subjects With Presbyopia

Change in driving scale score from preoperative to postoperative as measured by driving scale within PROWL-M was reported. PROWL-M driving scale consists of three driving related items that were used to generate the driving scale score. Each item response was converted to a 0 to 100 scale so that the lowest and highest possible scores were set at 0 (not functioning) and 100 (functioning) points. A high score represents better functioning. The composite driving scale score was calculated by averaging the scores of all the three items, resulting in a total score ranging from 0 to 100 where higher score represent better functioning. Change in driving scale score was defined as the driving scale score at 12-month visit minus the driving scale score at preoperative visit.

Percentage of participants who required secondary surgery to reverse monovision was reported.

Percentage of participants who experienced moderate to severe difficulty in activities was reported. Participants were asked questions about the difficulty they faced with daily activities, work or hobbies, reading, and judging distances. Responses was collected in 6 categories: (1) No difficulty at all, (2) A little difficulty, (3) moderate difficulty, (4) a lot of difficulty, (5) never try to do these activities because of vision, (6) Never do these activities for other reasons. Categories with non-zero data values are reported.

Percentage of participants who experienced satisfaction with vision was reported. Satisfaction with vision was assessed using a single-item question in the PROWL-M questionnaire. Participants were asked a question "In general, how satisfied or dissatisfied are you with your present vision". Responses was collected in 6 categories: (1) completely satisfied, (2) very satisfied, (3) somewhat satisfied, (4) somewhat dissatisfied, (5) very dissatisfied, (6) completely dissatisfied. Categories with non-zero data values are reported.

A questionnaire derived from the PROWL-M was given to participants after surgery. Satisfaction with LASIK via PROWL-M questionnaire was assessed with 8 items. Responses to individual items were linearly transformed to a 0 to 100 scale where 100 indicates best possible vision and satisfaction, while 0 indicates worst possible vision and satisfaction. Each item score was averaged together to produce a score ranging from 0 to 100. A higher score indicating greater satisfaction.

Percentage of participants who achieved 20/40 or better simultaneous binocular UCVA measured using Good-Lite 100 percent (%) proportionally spaced SLOAN letter/ETDRS charts designed for 4.0 meter (m) and the Good-Lite self-illuminated and self-calibrated illumination box were reported.
