Development of an in vitro model to assess posterior capsule safety during phacoemulsification with ultrasound or AquaLase handpieces

Abstract

This new experimental model in a cadaver eye provides a useful method for comparing factors and techniques that contribute to PC rupture.

Evaluation of the relationship between corneal diameter and lens diameter

“…This technique for gaining access to the posterior lens aspect has been described. 9 The horizontal and vertical dimensions of the crystalline lens were then measured ( Figure 2) and recorded for the horizontal and vertical meridians. Again, the same millimeter caliper was used and 3 measurements were made for each dimension and averaged.…”

Effects of pulsed fluid lens capsule washing following phacoemulsification on lens epithelial cells and posterior capsule opacification formation ex vivo

“…Adjustable parameters include fluid pulse rate and pulse magnitude. This capsule washing technology has been proposed to pose a decreased risk of posterior capsule rupture, when compared with conventional phacoemulsification needles due to its smooth polymer tip, and decreased risk of thermal incisional and intraocular tissue damage from nonthermal, fluid‐based technology …”

Liquefaction in the Prevention of Posterior Capsule Opacification–Safety and Efficacy

“…This technique was introduced by Alcon in late 2000, and together with an advanced ultrasound, NeoSoniX and OZil, is an option provided by INFINITI Vision System (Alcon Laboratories, Fort Worth, Texas, USA). Because the AquaLase tip is made of smooth material rounded-bevel polymer rather than metal, the risk for posterior capsule rupture is reduced, making this method more capsule friendly [5]. Several studies have shown that the technology may have applications in polishing the capsule through mechanical washing of lens epithelial cells (LECs) from the capsule bag with the fluid pulses [6,7].…”
