Purpose. To report visual performance and quality of life after implantation of a bifocal diffractive multifocal intraocular lens (MIOL) in postmyopic laser in situ keratomileusis (LASIK) patients. Methods. Prospective, observational case series. Patients with prior myopic LASIK who had implantation of Tecnis ZMA00/ZMB00 MIOL (Abbott Medical Optics) at Hong Kong Sanatorium and Hospital were inc...

PURPOSE To describe the results of cataract extraction with toric intraocular lens (IOL) implantation in patients with preexisting astigmatism from three corneal conditions (keratoconus, postkeratoplasty, and postpterygium surgery). METHODS Cataract patients with topographically stable, fairly regular (although sometimes very high) corneal astigmatism underwent phacoemulsification with implan...

Purpose To analyze the "in vitro" aberrometric pattern of a refractive IOL and two extended depth of focus IOLs. Methods A special optical bench with a Shack-Hartmann wavefront sensor (SH) was designed for the measurement. Three presbyopia correction IOLs were analyzed: Mini WELL (MW), TECNIS Symfony ZXR00 (SYM), and Lentis Mplus X LS-313 MF30 (MP). Three different pupil sizes were used for t...

The choices of intraocular lenses (IOLs) available for implantation in cataract patients are multitudinous. Each option features significant benefits for visual performance and the comfort of the patients, but there are also some inherent limitations in each case. The traditional approach of monofocal IOL implantation is effective in providing adequate distance visual acuity, but is limited in ...

Aim . Analysis of the functional results new IOL with an extended depth focus implantation a in short-term (6 months) follow-up period. Patients and methods The prospective study included 27 patients (40 eyes) after bilateral (n = 12) or monolateral 15) EDOF Tecnis Symfony average period 6.5 ± 0.2 (6–7) months. In all cases, was preceded by cataract phacoemulsification removal transparent lens ...

PURPOSE To assess through-focus polychromatic image sharpness of five US Food and Drug Administration-approved presbyopia-correcting intraocular lenses (IOLs) through a range of object vergences and pupil diameters utilizing an image sharpness algorithm. METHODS A 1951 US Air Force resolution target was imaged through a Crystalens AO (AO) (Bausch & Lomb Surgical, Aliso Viejo, California), Cry...

PURPOSE To analyze the post operative results of targeting zero spherical aberration by selecting the best-fit aspheric intraocular lens (IOL), based on preoperative corneal spherical aberration of patients with phacoemulsification surgery. SETTING AlHokama Eye Specialist Center, Riyadh, Saudi Arabia. PERIOD From the 1st of October 2012 until the 10th of April 2013. METHODS Fifty-three ey...

s for within person RCTs should indicate the paired or within person nature of the trial. Table 1⇓ shows the minimum information that should be included in the abstract of a within person trial, in addition to the items recommended for all trials. We were not able to find examples of good reporting that tackled all the items required. We therefore developed an example abstract by enhancing a pu...
