TLDR
Soft acrylic IOLs have clinically apparent advantages in small incision cataract surgery and remain quite stable throughout the 2 year follow‐up period, with axis‐based astigmatism remaining quite stable.Abstract:
Purpose: To assess the efficacy and safety of a soft acrylic intraocular lens (IOL) in small incision cataract surgery. Methods: Sixty-four eyes of 64 patients (mean age 71.0 ± 7.7 [SD] years) who had phacoemulsification and implantation of a soft acrylic IOL were followed for 2 years. Results: At day 1, 96.9% of patients had corrected visual acuity of 20/40 or better, and 50.0% had 20/20 or better. At 2 years postoperatively, 100% had 20/40 or better, and 86.3% had 20/20. Surgically induced keratometric cylinder remained quite stable throughout the 2 year follow-up period, with axis-based astigmatism of ±0.3 diopters. Flare intensity measured with the laser flare-cell meter was less than that with other type of IOLs measured, including poly(methyl methacrylate) and silicone. Neodymium:YAG laser capsulotomy was performed in seven cases (11.1 %) without causing damage to the optic. No other postoperative complications were encountered. Conclusion: Soft acrylic IOLs have clinically apparent advantages in small incision cataract surgery.read more

TL;DR: Intraocular lenses made from AcrySof were associated with a significantly reduced degree of PCO, and was associated with less PCO than PMMA, silicone, and silicone lenses analyzed 2 years postoperatively.

TL;DR: Intraocular lenses made from polyacrylic are associated with a significantly reduced degree of PCO and lower YAG rates 3 years after surgery, and the visual acuity and contrast sensitivity were not significantly different among the three groups if patients with age-related macular degeneration and those requiring YAG capsulotomies are excluded.

TL;DR: In this article, the authors report the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy rate (%) of eight rigid and foldable intraocular lens (IOL) designs in a series of 5416 pseudophakic human eyes obtained postmortem, accessioned in a center between January 1988 and January 2000.

Preventing posterior capsule opacification by creating a discontinuous sharp bend in the capsule.
Okihiro Nishi,Kayo Nishi +1 more
TL;DR: The discontinuous sharp capsule bend created by the sharp optic edges in both IOL types appeared to induce contact inhibition of the migrating LECs, and the preventive effect of an acrylic IOL on posterior capsule opacification may be design dependent.

Adhesion of lens capsule to intraocular lenses of polymethylmethacrylate, silicone, and acrylic foldable materials: an experimental study
TL;DR: The acrylic foldable IOL adhered to the lens capsule more than the PMMA IOL, and the silicone IOL showed no adhesiveness, which seems to play a role in preventing lens epithelial cells from migrating and forming posterior capsule opacification.

TL;DR: Clinical, pathological and experimental studies have shown that use of hydrodissection, the continuous curvilinear capsulorhexis and specific IOL designs may help reduce the incidence of this complication, and various pharmacological and immunological methods are being investigated.

A new method of analyzing vectors for changes in astigmatism
TL;DR: This method of astigmatism analysis recognizes the need to define anAstigmatism goal, thus allowing the surgeon to obtain precise, separate measures of the magnitude and the angle of surgical error, allowing statistical comparison of multiple surgeries and techniques.

New quantitative method to determine protein concentration and cell number in aqueous in vivo.
TL;DR: This new method of determining protein concentration and cell number in the aqueous enabled us to make a noninvasive and quantitative evaluation of the inflammation in the anterior segment of the eye.

Astigmatism after small incision cataract surgery. A prospective, randomized, multicenter comparison of 4- and 6.5-mm incisions.
TL;DR: Subgroup analysis of the suturing technique showed that the technique of wound closure, as well as the wound size, influenced the induced astigmatism, however, the variability in the amount of induced cylinder was least with the 4.0-mm wound.
