PURPOSE To compare lens orientation and rotational recovery of five currently available soft toric lenses. METHODS Twenty subjects were recruited and trialed with each of the study lenses in a random order. Study lenses were PureVision(®) Toric (B&L), Air Optix(®) for Astigmatism (Alcon), Biofinity(®) Toric (CooperVision), Acuvue(®) Advance for Astigmatism (Vistakon), and Proclear(®) Toric (C...

Aims To report on 4-year postoperative visual performance with the toric implantable collamer lens (TICL) for stable keratoconus after sequential procedure (corneal collagen crosslinking plus TICL implantation). Methods Forty eyes of 24 patients with stable keratoconus with myopia between 0.00 and -18.00 dioptres (D) and astigmatism between 1.25 and 8.00 D were evaluated in this prospective i...

PURPOSE To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction. MATERIALS AND METHODS The study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of th...

BACKGROUND To use a Monte Carlo simulation to predict postoperative results with the AcrySof Toric lens, evaluating the likelihood of over- or under-correction using various toric lens selection criteria. METHODS Keratometric data were obtained from a large patient population with preoperative corneal astigmatism <= 2.50D (2,000 eyes). The probability distributions for toric marking accuracy,...

Combined Posterior Phakic Intraocular Lens and SMILE in a Patient With High Myopia Bioptics is defined as a sequential method of treating large and complex refractive errors aiming to improve stability and predictability by the combination of refractive techniques with different mechanisms of action.1 The Visian Implantable Collamer Lens (ICL; STAAR Surgical, Monrovia, CA) is a foldable phakic ...
