ACCOMMODATION

Convergence accommodation.

Steady-state accommodation responses were measured in both eyes as a function of vergence angle and direction of lateral gaze. The measurements were made with a binocular laser optometer. Small speckle patterns were used as fusional stimuli in an otherwise dark field. These patterns have the advantage of providing no blur stimulus to accommodation. Convergence accommodation for vergence angles ...

The surgical correction of presbyopia : Accommodation , pseudo - accommodation or multifocality ?

“It is undoubtedly the final frontier of cataract and refractive surgery.There is great interest and excitement in this field of research at the moment and we are seeing some very interesting approaches coming on stream which hold great promise for future treatment of presbyopia,” said David Spalton FRCS, FRCOphth, who co-chaired the symposium. Dr Spalton said it was important to remember that ...

Obstacle accommodation motion planning

A new robot path planning methodology called obstacle accommodation has been introduced for robots in cluttered environments. This methodology does not attempt to avoid physical contact between a robot and obstacles. Instead, it controls the contact to prevent damage to the robot. Obstacle accommodation represents a new robotic paradigm in which obstacles can contact robots at unspecified posit...

The Development of Accommodation

We investigated the roles that blur, proximity and vergence cues play in the development of accommodation. Accommodative responses to targets incorporating one or more of these cues were measured for four adults and eight infants at 1.5 and 3 months of age using eccentric photorefraction. Adults showed accurate accommodation to blur cues, and variable accommodation with proximity cues alone. So...
