A cortical cataract begins as whitish, wedge-shaped opacities or streaks on the outer edge of the lens cortex. As it slowly progresses, the streaks extend to the center and interfere with light passing through the center of the lens.
The residual lens cortex was removed by a vitreous cutter with reduced cutting rate of 800 cuts/min.
And at the end of the 18th day, more than 85% lenses of control group were milky both in the lens cortex and in the nuclear; most of galactosemic lenses were at stage 5.
Slitlamp biomicroscopy revealed normal depth of the anterior chamber, an intact anterior capsule, and a ruptured posterior capsule (transversely in 1 eye and longitudinally in 3 eyes, Figure 1) with or without vitreous prolapse into the opaque lens cortex. Fibrosis of the capsular rupture was observed in all the cases except Case 1 during surgery.
Lens cortex removal was done as completely as possible without endangering the integrity of the capsular bag enclosing the lens remnants (if a capsular bag was present).
Among the vital stains, brilliant cresyl blue has never been used in vivo; the gentian violet and methylene blue solutions result in corneal edema and endothelial decompensation, fluorescein must be injected underneath the anterior capsule, staining the lens epithelium, not the capsule itself and it can stain the cornea and lens cortex also.
The anterior capsule of the lens can become compromised, allowing proteins from the lens cortex to be released into the anterior chamber.
These accumulation processes form a strong adhesion between the lens cortex and capsule.
