Zonular traction tufts are found in 15% of eyes and are thin strands of retina that extends at an acute angle from the peripheral retina.
This theory states that the optical power of the crystalline lens is increased by relaxation of the tension on these zonules, while an increase in zonular tension causes a decrease in optical power.
This increased equatorial zonular tension expands the equatorial diameter of the lens, alters the surface curvatures of the lens and, thereby, increases the central optical power of the lens.
10) Zonular fibres support the capsule and any condition that weakens those fibres could lead the lens to dislocate.
It has been found to be a significant factor in planning cataract surgery, as it is associated with zonular weakness and a higher frequency of intra-operative complications during cataract surgery, including rupture of the posterior lens capsule, zonular dialysis and a rise in IOP occurring postoperatively.
This involved creating a large 180[degree] limbal incision and removing the lens together with the capsule by breaking the zonular ligaments.
Previously, cases of severe zonular compromise required ECCE, ICCE or pars plane lensectomy, a procedure which involves the removal of the entire lens within the pupillary area (the anterior capsule, anterior cortex, nucleus, posterior cortex, and posterior capsule).
