In this research the factors used to evaluate the light transmission through two types of acrylic hydrophobic intraocular lenses, one that contained yellow chromophore that blocks blue light transmission and the other which did not contain that filter, were defined according to various light condition, e.g., daylight and at night. The potential influence of light transmission trough intraocular...

Intraocular lens (IOL) is an artificial lens implanted into the eye. It usually replaces the existing crystalline lens, which is clouded over due to a cataract. In order to evaluate the optical performance of different IOLs an optomechanical model of human eye was developed. This model closely reproduces anatomical and optical properties of the average human eye. This makes it possible to measu...

purpose : to investigate long-term visual outcome and complications after cataract extraction and intraocular lens (iol) implantation in fuchs’ heterochromic iridocyclitis (fhi) methods : in this retrospective study in a private eye clinic in tehran, 25 eyes of 24 patients with fhi who underwent cataract extraction and iol implantation were evaluated based on their visual outcome and intraopera...

purpose : to compare results of different methods for true corneal power determination and intraocular lens (iol) power calculation formulas in 10 eyes of 7 patients with previous radial keratotomy (rk) with or without astigmatic keratotomy methods : in this case series study, we determined the corneal power of 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy wit...

BACKGROUND To evaluate the rotational stability of the three types of AcrySof SA60TT toric intraocular lenses (Alcon, Switzerland) in cataract surgery after the first postoperative week. METHODS A retrospective study of 44 eyes in 33 patients. All patients underwent similar uncomplicated phacoemulsification cataract surgery. Seven eyes with corneal astigmatism of less than 1.5 D were implante...
