The Primary Posterior Continuous Curvilinear Capsulorhexis

open access: yes, 2017
The lens capsule is the thickest basement membrane in the body and develops from the lens epithelial cells to encapsulate the lens fibers. The thickness of the capsule is highly variable and is thinnest at the posterior face. At 9 μ in thickness, it is significantly thinner than its anterior counterpart [1]. The capsule consists of a thin, transparent,

Continuous Curvilinear Capsulorhexis – A Practical Review

Seminars in Ophthalmology, 2022
Continuous curvilinear capsulorhexis (CCC) has become the gold standard technique for anterior capsulotomy, a cardinal development in modern cataract surgery. CCC enables safer and relatively convenient access to the crystalline lens, however it is more challenging to master than older methods. Understanding the physics underlying this procedure is key

Evaluation of continuous curvilinear capsulorhexis based on a neural-network

International Journal of Computer Assisted Radiology and Surgery, 2023
Continuous curvilinear capsulorhexis (CCC), as a prerequisite for successful cataract surgery, is one of the most important and difficult steps in phacoemulsification. In clinical practice, the size and circularity of the capsular tear and eccentricity with the lens are often employed as indicators to evaluate the effect of CCC.We present a neural ...

Operation behaviours of surgical forceps in continuous curvilinear capsulorhexis

International Journal of Medical Robotics and Computer Assisted Surgery, 2022
AbstractBackgroundContinuous curvilinear capsulorhexis (CCC) is a delicate ophthalmic procedure which may benefit from robot technology. Measuring the behaviours (physiological tremor, operation force) of surgeons provides baseline data to develop assistive CCC robot.MethodsA forceps with fibre bragg grating and inertial sensors is used to measure the ...

Continuous curvilinear capsulorhexis with use of an endoscope

Journal of Cataract and Refractive Surgery, 2004
We describe a technique for creating a continuous curvilinear capsulorhexis (CCC) using an endoscope. Three 2.0 mm limbal incisions 120 degrees apart were made in 4 cadaver eyes. The anterior capsule was stained with trypan blue 0.1% (Vision Blue). Under endoscopic visualization, a CCC was attempted in each of the 4 globes.

Forceps-puncture continuous curvilinear capsulorhexis

Journal of Cataract and Refractive Surgery, 1997
Forceps-puncture continuous curvilinear capsulorhexis uses a single instrument. Using less instrumentation during the procedure decreases the chance of inadvertent damage to ocular structures and reduces surgical time. Complications related to this technique are rare.
