Sorry, even if the cataractous nucleus is sucked out leaving the cortex with its epithelial cells to regenerate a new nucleus, surgery is still needed. And what do we do for those months until the new nucleus grows in? We would be visually disabled. No, no, no. I believe the best solution is to restore clarity to the old nucleus, by means of eyedrops that re-activate the dormant alpha-crystallin in the cortex. The re-activated alpha-crystallin will then slowly untangle the clumps of beta- and gamma-crystallins in the nucleus, and restore its clarity.
