Attaining Perfect Vision with CCC technique in Cataract Surgery

Traditionally, the surgeons were opening the capsule of the lens of an eye to treat cataract and they used to extract the lens and the capsule to prevent any possible inflammation after surgery due to leftover parts.

Modern cataract surgeries are no longer extracting the entire capsule with the introduction of a modern technique called continuous curvilinear capsulorhexis (CCC). Modern day surgeons are able to remove the entire residual left after the surgery with this technique. Surgeons used to remove the affected layer along with the capsule in the past. With the introduction of Intraocular Lens (IOL), the ophthalmologist is able to remove the entire affected layer while retaining the capsule. The implanted lens however, may vary from surgeon to surgeon and depending upon the type of IOL implanted; there will be a 360◦ optic overlap. While excessive overlap may cause a postoperative hyperopic shift, incomplete overlap is associated with IOL tilt, causing lack of clarity in the vision. 

According to a study called Impact of Capsulorhexis Morphology on the Predictability of Intraocular Lens Power Calculations, Jonathan M Davidorf argues that compared to acceptably shaped CCCs, a perfectly centered, perfectly round anterior capsulotomy will improve the predictability of the effective lens position. The study reviewed 175 random cataract surgery videos (acrylic IOL) to assess the impact of capsulorhexis (CCC) morphology on predictability of intraocular lens (IOL) calculations. The study found no significant difference in variance and concludes that there appears to be no relationship between CCC morphology and IOL calculation predictability.
