Table 1 Summary of the critical changes during accommodation
From: Accommodative intraocular lenses: where are we and where we are going
Accommodated eye |
1. Sphincter-like action of circular muscle fibers contraction |
2. Contraction of ciliary muscle |
3. Distance between edges of ciliary body decreases |
4. Relaxation of suspensory ligament |
5. Lens becomes thicker |
6. Focal length shortens |
Unaccommodated eye |
1. The ciliary muscle is relaxed |
2. Aqueous and vitreous humor push outward on the sclerotic coat |
3. Ligaments become taut/tensed |
4. Lens pulled into a thin shape |
5. Focal length becomes short |
