monovision - ANSWER-dependent on the ability of the brain to suppress blur from defocused eye ghost images and fluctuating vision - ANSWER-through monovision, patients are able to avoid ______ and _______ due to change of pupil size. stereopsis - ANSWER-#1 problem with monovision is loss of ________________ alternating/translating or spheric spheric = aspheric and concentric - ANSWER-Which lens designs are multifocal? alternating/translating - fit = slightly flatter than "K" - ANSWER-Which multifocal only has one zone of vision in front of the pupil at one time? How is this lens normally fit on the eye? At or within 1mm below the lower pupil margin - ANSWER-How should the segment line be positioned for an alternating/translating GP? lens is too steep = flatten BC - ANSWER-If your patient has a translating lens on and it is rotating too much, what does this mean and how would you troubleshoot it? nose - ANSWER-With alternating lens, rotation towards what direction would be okay? increase prism ballast by 0.5D - ANSWER-If your patient is wearing a translating lens and you notice that the segment is too high, how would you troubleshoot this problem? simultaneous ~ limited movement is desirable - ANSWER-Which multifocal lens design is *pupil dependent*? empirical - ANSWER-What is the best way to fit a patient into a simultaneous multifocal lens? 0.75-1.5D steeper than K limited movement = desirable - ANSWER-How are simultaneous designed lenses fit? low eccentricity (lower rate of change in flattening) - less plus in periphery - conventional fit - distance vision less compromised high eccentricity (higher rate of change in flattening) - more plus in periphery - steeper than "K" fit - distance vision is compromised - ANSWER-low vs high eccentricity Back Surface Aspheric Lense
