During a typical day, the presbyopic patient popu- lation spent an average of 4.4 hours per using a com- puter/laptop at work and an average of 1.7 hours at home (Table 2). In addition, other digital devices (smartphone/tablet/e-reader) were used an average of 1.9 hours per day. Of those surveyed, the least amount of time was spent playing electronic games. THE PRESBYOPIC PATIENT'S EXPERIENCE To obtain real-world user experience, patients re- sponded to a web-based subjective assessment of lens performance after 5 days of lens wear. This assessment was completed outside of the practitioner's office to help ensure a higher level of objectivity. Presbyopic patients were asked to rate their ease of seeing objects at various distances with their habitual vision correction and with the Bausch + Lomb Ultra for Presbyopia contact lens. Figure 2 summarizes the responses for the 344 presbyopic patients who previ- ously wore contact lenses. A greater proportion of contact lens wearers reported that near, intermediate, and distant objects were easy to see when wearing the Bausch + Lomb Ultra for Presbyopia contact lens com- pared with their habitual correction. The contact lens wearers were asked to rate their expe- rience with comfortable vision for specific distance situa- tions, general situations, and for different lighting condi- tions. Comfortable vision was defined for the patients as "being able to see clearly without a compromise in the comfort of your contact lenses." Responses regarding the wearing experience related to various vision situations are presented in Table 3. For this habitual contact lens group, tion with lens wear in presbyopic patients were key priorities. Top drivers of overall satisfaction are sharp, clear vision at near and mid-range distances. Ease of transition between near and far and comfort throughout the day also play a major role in the de- gree of satisfaction (Multi-sponsor Surveys, Inc., 2015). The 3-Zone Progressive Design integrated into the Bausch + Lomb Ultra for Presbyopia contact lens used a broad investigational approach that accounted for re- fractive error, higher-order aberrations, pupil diameter, corneal curvature, axial length, and residual accommo- dation across nine distances to optimize vision at near, mid-range, and distant distances. The MoistureSeal tech- nology of the Bausch + Lomb Ultra for Presbyopia con- tact lens is used to hold water throughout the bulk and at the surface of the lens by permanently surrounding the silicone matrix with the water-loving polymer PVP to pro- vide all-day comfort. The aim of this survey was to obtain information regarding presbyopic patient acceptance and satisfaction with the Bausch + Lomb Ultra for Presbyopia multifocal contact lens. THE PRESBYOPIC PATIENT COHORT Independent eyecare practitioners from across the United States fitted pres- byopic patients as part of their routine practice. Practitioners were given instruction on the Bausch + Lomb Ultra for Presbyopia contact lens and its recommended fit guide. Patients were asked to complete an online survey regarding their perspec- tives on lens performance. Four hundred and thirty-seven presbyopic patients were fitted with the Bausch + Lomb Ultra for Presbyopia contact lens; 78% were female and 22% were male. The majority of patients were between the ages of 41 and 60 (Table 1).
