Intraocular lenses

Ahmad A Aref
PURPOSE OF REVIEW: Sustained drug delivery has been recognized as a need for patients with ocular hypertension or glaucomatous optic neuropathy. Several sustained drug delivery systems and devices are currently on the horizon. This review aims to summarize initial results with these platforms, as reported in the literature, and also provide insight into their possible role in the glaucoma treatment paradigm. RECENT FINDINGS: Sustained drug delivery systems currently on the horizon include the topical bimatoprost ocular insert, travoprost and latanoprost punctal plugs, latanoprost-eluting contact lenses, bimatoprost and travoprost intraocular implants, as well as several other therapies in earlier stages of development...

Purpose: To quantify the effect of induced stray light on halo size, luminance threshold, and contrast sensitivity. Methods: Retinal stray light was induced in five healthy subjects using different photographic filters. The stray light induced ranged from levels observed in intraocular lenses (IOLs) with glistenings (low) to cataract level (high). The visual impact was measured for halo size, luminance detection threshold, and contrast sensitivity with and without a glare source...

Currently, infections following cataract surgery are not as effectively managed with antibiotic eye drops, which suffer from poor bioavailability of drug and low patient compliance. The ideal solution, which can help to overcome the issue of drug wastage and poor bioavailabilty, as well as the need for frequent applications (patient inconvenience), is a drug-eluting intraocular lens (IOL). We describe a novel approach to such a drug-eluting lens by using a peripheral IOL attachment as a drug depot to deliver antibiotics, Levofloxacin (LFX) or Moxifloxacin (MFX)...

PURPOSE: Secondary intraocular lens (IOL) placement in uveitic eyes is challenging. We describe a series of sclerally fixated IOLs using a transconjunctival sutureless (SIS) technique in eyes with history of uveitis. METHODS: This is an interventional, retrospective, consecutive case series. RESULTS: Five patients with a history of well-controlled uveitis were included. All underwent vitrectomy, with removal of residual lens fragments if necessary...

PURPOSE: To investigate the visual outcomes between mix-and-match bifocal intraocular lenses (IOLs) (ReSTOR +2.50 and +3.00 diopters [D]; Alcon Laboratories, Inc., Fort Worth, TX) versus bilateral implantation of a trifocal IOL (FineVision; PhysIOL, Liège, Belgium). METHODS: Twenty-three patients (average age: 56.3 ± 6.9 years; range: 45 to 71 years) referred for lens phacoemulsification and IOL implantation were included in this study. Patients were randomly assigned to two groups...

PURPOSE: To analyze intraocular lens (IOL) orientation data from an online toric back-calculator ( for determining if differences were apparent by lens type. METHODS: A retrospective review of toric back-calculations that included IOL identification and intended orientation axis. RESULTS: Of 12,812 total validated calculation records, 8,229 included intended orientation and lens identification data. Of the latter, 5,674 calculations (69%) involved lenses oriented 5° or more from their intended position...

PURPOSE: To compare the optical performance of 3 trifocal intraocular lenses (IOLs): the Acrysof IQ Panoptix (+2.17 diopter [D]/+3.25 D IOL), AT LISA Tri 839MP (+1.66 D/+3.33 D IOL), and Finevision Micro F (+1.75 D/+3.50 D IOL). SETTING: Alcon Research Ltd., Fort Worth, Texas, USA. DESIGN: Experimental study. METHODS: The 3 trifocal IOLs were compared using optical performance tests. To measure image quality, through-focus modulation transfer function (MTF) curves were generated for a model eye...

PURPOSE: To test the hypothesis that binocular depth of field can be expanded while retaining high-quality vision at intermediate distances by combining anisometropia (monovision) and simultaneous vision bifocals. SETTING: School of Optometry, Indiana University, Bloomington, Indiana, USA. DESIGN: Prospective research study. METHODS: A computational polychromatic model was used to simulate retinal images as seen through a pseudophakic eye with a diffractive bifocal for a range of target distances...

Cataract, a degradation of the optical quality of the crystalline lens, progressive and age-related, is the leading cause of treatable blindness worldwide. Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed the primary concern of cataract surgery to become a procedure refined to yield the best possible refractive results...

INTRODUCTION: Toric intraocular lenses (IOLs) are an effective way of compensating preexisting corneal astigmatism during cataract surgery. To achieve success, it is imperative to align the toric IOLs in desired position and preoperative reference marking is one among the three important steps for accurate alignment. To make the marking procedure simpler and effective, we have modified the conventional three-step slit lamp-based technique. MATERIALS AND METHODS: Patient is seated in front of the slit lamp and asked to keep the chin over chin rest...

PURPOSE: To assess the outcomes of sulcus implantation of the Visian(®) implantable collamer lens (ICL) to correct pseudophakic myopic anisometropic amblyopia with myopic shift and/or primary refractive overcorrection. METHODS: Prospective case series enrolled 14 pseudophakic eyes of 14 patients, 5-9 years old, with history of cataract surgery and primary in the bag-intraocular lenses (IOL) implantation, followed by myopic shift and/or refractive overcorrection and anisometropic amblyopia of variable degrees...

PURPOSE: This study was initiated to introduce the term non-corneal ocular residual astigmatism (N-CORA) as a new parameter in astigmatic change analysis after implantation of two different types of non-toric, multifocal intraocular lenses (MIOL). METHODS: Seventy-two eyes from 72 consecutive patients after MIOL surgery were studied in terms of a retrospective, cross-sectional data analysis. Two types of spherical MIOL were used. Surgical technique in all patients was a 2...

PURPOSE: To compare the longitudinal vault changes after implantation of a posterior chamber phakic intraocular lens (pIOL) (Visian Implantable Contact Lens) with (ICL V4c) and without (ICL V4) a central artificial hole for moderate to high myopia in Chinese eyes. DESIGN: Retrospective case series. METHODS: This study comprised 78 eyes implanted with the ICL V4c model and 82 eyes implanted with the ICL V4 model at our department by the same surgeon...

PURPOSE: To prospectively compare postoperative results of two premium intraocular lenses EnVISTA (Bausch and Lomb) and AcrySof IQ (Alcon), focussing on glistenings and posterior capsule opacification. The evaluation of glistenings was done using Image J software and posterior capsule opacifications were quantified with OSCA system. METHODS: Twenty patients (7 men and 13 women) with bilateral cataract were included. EnVista intraocular lens (IOL) was implanted in one eye and AcrySof IQ IOL in the second eye of each patient...
