“…In Percival & Setty's (1988) study the incidence of capsulotomy for 3 years of follow-up varied from 4.7% for eyes with implanted PCL's to 40% for eyes without implants. We found a total need for capsulotomy of 24%.…”

Morphological changes and lens position were examined in 51 eyes of 51 patients 25 to 37 (mean 31) months after extracapsular cataract extraction with implantation of a posterior chamber lens in the ciliary sulcus. Ocular morphology was compared to a previously published examination of the same eyes performed 4 months after surgery. The anterior chamber depth, lens position and the position of the posterior lens capsule had remained unchanged. 'Iris bulging', i.e. a gonioscopically visible slight impression of the iris overlying the lens haptics, had increased from 0 to 42%, iridal transillumination defects from 34 to 46%, and pigment dispersion in the chamber angle from 46 to 72%. Twenty-four percent of the eyes had developed significant, capsulotomy-requiring opacification of the posterior lens capsule. We draw the following conclusions: The posterior chamber lens and the posterior lens capsule have reached their permanent positions by the fourth post-operative month. Implantation of a posterior chamber lens in the ciliary sulcus constitutes a constant stimulus for structural changes of the iris with subsequent dispersion of pigment on neighbouring ocular structures.

“…In a study by Percival & Setty (1988), it was found that extracapsular cataract extraction led to a YAG capsulotomy by five years in 49% of the eyes without lens implant, in 23% of eyes with a Binkhorst iridocapsular lens, and in 13% of eyes that had received a posterior chamber lens. The surface area of the posterior chamber lens was considered to be an important factor in inhibiting capsule opacification.…”

This study was designed to determine whether different factors could influence the formation of posterior capsular opacities. The study group comprised 271 patients who had undergone an extracapsular cataract extraction with implantation of a posterior chamber lens either with or without laser ridge. Between 12 and 25 months after surgery, a statistically significant difference was found with a lower rate of secondary cataract in the laser ridge group, but with respect to advanced secondary cataract, i.e. eyes which needed YAG capsulotomy, no statistically significant difference was found (Fvalue 0.99). No association was found between age or sex of patients, different surgeons or complications during or after surgery and the risk of getting a secondary cataract.

“…Posterior capsule opacification (PCO) is one of the most common complications of cataract extraction with intraocular lens (IOL) implantation, occurring in 36% to 97% of cases in the first 2-4 years after extracapsular cataract surgery [1][2][3][4][5][6] . Since the PCO usually develops over years and leads to a slow decrease in visual acuity (VA), progression over time is the important factor in PCO evaluation 7 .…”

Aim.To compare the degree of posterior capsule opacification (PCO) after AquaLase and NeoSoniX phacoemulsification methods during an 8-year follow-up period using two types of software. Design. Prospective, randomized clinical trial. Methods. AquaLase was used in the right eye and NeoSoniX in the left eye of each patient with bilateral cataract. Results. Fifty patients were analyzed 1 year, 46 patients 3 years, and 37 patients 8 years after cataract surgery. Mean EPCO 2000 values were for the AquaLase group 0.324 ± 0.305 and for the NeoSoniX group 0.298 ± 0.341 (P = 0.53) 1 year after surgery, for the AquaLase group 0.582 ± 0.506 and for the NeoSoniX group 0.594 ± 0.515 (P = 0.87) 3 years after surgery, and for the AquaLase group 0.648 ± 0.567 and for the NeoSoniX group 0.673 ± 0.542 (P = 0.30) 8 years after surgery. The OSCA results were for the AquaLase group 0.7097 ± 0.3778 and for the NeoSoniX group 0.8584 ± 0.4323 (P = 0.046) 1 year after surgery, for the AquaLase group 0.9667 ± 0.736 and for the NeoSoniX group 0.9540 ± 0.5250 (P = 0.91) 3 years after surgery, and for the AquaLase group 1,035 ± 0,952 and for the NeoSoniX group 1,103 ± 0,741 (P = 0.44) 8 years after surgery. Conclusion. There was minimal PCO difference between these 2 approaches, AquaLase and NeoSoniX. Neither AquaLase nor NeoSoniX technique was able to prevent a natural progression of PCO.
