Instead of conventional phacoemulsification, the lens nucleus
underwent hydrodis-section and extracted manually; then an aspiration device was used to remove the cortex through the auxiliary incision.
Nuclear cataracts are the most common type of cataracts and involve the yellowing of the lens nucleus
. Along with various mechanisms, each type of cataract has different associated risk factors .
(13) Peyman and Katoh in 1987 used an Erbium:YAG laser for inducing photoablation on the lens nucleus
. (14) However, these pioneering procedures did not gain popularity due to complications and preference for conventional phacoemulsification.
(2) published their finding of a highly statistical significant relationship between opalescent quality and color of lens nucleus
on the mechanical compression character of cataractous lens.
There remains a concern, however, that it may be unsuitable for some cataracts because of the advanced maturity and hardness of the lens nucleus
4), but not to the diameter of the larval eye lens nucleus
, which in Figure 3 was identified with a diameter of 50 [micro]m.
Upon examination 'sugar cracks' going largely through the central lens nucleus
were noted, (38) and early signs of posterior subcapsular opacification were present too.
This crucial restriction means that the proteins of the lens nucleus
remain as they were formed in utero, and are vulnerable to damage by chemical changes (post-translational modification).
