We report on a patient with postsurgical cystoid macular edema (CME) after phacoemulsification and multifocal intraocular lens (MIOL) implantation. At first, there was a very good reaction to intravitreal triamcinolone, inducing complete regression of the edema without increasing intraocular pressure (IOP). One year later the patient suffered from retinal detachment and was treated with vitrectomy, laser, and gas tamponade. Afterward, he developed macular pucker with edema. After surgical treatment with pucker peeling and intravitreal triamcinolone, the patient showed a steroid response and an increase IOP...

BACKGROUND: Healthy ageing is accompanied by simultaneous decline of visual and neural function. Studies in animals and humans provide converging evidence that these functions' decrease is mostly associated with structural change in ocular and brain structure. We investigated whether regaining visual function after ocular reconstruction was associated with functional and structural changes in the brain. METHODS: We did a prospective controlled clinical trial including 21 consecutive typical ageing patients (42 eyes; mean age 63·14 years, SD 7·82) with decreased visual function and diagnosis of bilateral age-related cataracts requiring phacoemulsification surgery and multifocal or monofocal intraocular lens implantation...

We report the first case of toric multifocal intraocular lens (IOL) implantation in both the eyes of a young patient of Alport syndrome with anterior and posterior lenticonus with a successful outcome. An 18-year-old female patient presented with progressively blurred vision in both eyes since 4-5 years not improving with glasses. Refraction showed high myopia with astigmatism; however, the vision did not improve beyond 6/60 with glasses correction. Clinical examination on slit lamp showed anterior and posterior lenticonus bilaterally with a classical oil droplet appearance...

BACKGROUND: Good unaided distance visual acuity (VA) is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision, however, still requires additional refractive power, usually in the form of reading glasses. Multiple optic (multifocal) IOLs are available which claim to allow good vision at a range of distances. It is unclear whether this benefit outweighs the optical compromises inherent in multifocal IOLs. OBJECTIVES: To assess the visual effects of multifocal IOLs in comparison with the current standard treatment of monofocal lens implantation...

BACKGROUND: Refractive lens exchange and implantation of a multifocal intraocular lens (MIOL) is mainly advised for ametropes with presbyopia. Non-presbyopic young ametropes who wish spectacle-independence are usually treated with corneal refractive surgery or phakic lenses. OBJECTIVES: This retrospective case series aimed to analyse the refractive and subjective satisfaction outcome after MIOL surgery in both eyes of non-presbyopic ametropes where other treatment options were not possible...

Improved efficacy, predictability, and safety of modern phacoemulsification have resulted in cataract surgery being considered as a refractive procedure. Refractive lens exchange by definition is a surgery aimed at replacing the cataractous or clear crystalline lens with an intraocular lens (IOL) in cases of high ametropia. The excellent intraocular optics of this procedure provide a better visual outcome as compared with laser refractive surgery in high myopia. With advances in technology and IOL formulas, the predictability of refractive outcome after cataract surgery in high myopes has improved...

We present and test a methodology for generating simultaneous vision with a deformable mirror that changed shape at 50 Hz between two vergences: 0 D (far vision) and -2.5 D (near vision). Different bifocal designs, including toric and combinations of spherical aberration, were simulated and assessed objectively. We found that typical corneal aberrations of a 60-year-old subject changes the shape of objective through-focus curves of a perfect bifocal lens. This methodology can be used to investigate subjective visual performance for different multifocal contact or intraocular lens designs...

PURPOSE OF REVIEW: The manuscript presents a review of recently published studies reporting objective and subjective outcomes and preoperative considerations of asymmetrical multifocal intraocular lenses (IOLs). RECENT FINDINGS: Current publications suggest that asymmetrical multifocal IOLs provide good, distance, intermediate and near vision for cataract and clear lens extraction patients. The contrast sensitivity achieved is similar to monofocal IOLs. Photopic phenomenon such as glare and halos has been reduced through the use of these IOLs leading to better patient satisfaction...

PURPOSE: To compare the long-term results of a secondary sulcus-placed, multifocal add-on intraocular lens (IOL) with those of a multifocal IOL implanted in the capsular bag. METHODS: In this prospective clinical trial, 30 pseudophakic eyes were treated with a multifocal add-on IOL and 30 cataractous eyes with a standard multifocal IOL. The main outcome measures comprised manifest refraction, visual acuity, defocus curves, and contrast sensitivity. Patients who had bilateral implantation of the same lens type were asked to complete a questionnaire...

We performed a literature review comparing multifocal intraocular lens (IOL) implantation with pseudophakic monovision to treat presbyopia. Multifocal IOLs utilize refractive or diffractive principles to treat both distance and near vision, with a single lens implant. Monovision uses traditional monofocal lens implants to treat the dominant eye for emmotropia, and the non-dominant eye for myopia. This planned anisometropia is designed to enhance intermediate or near vision. Generally, distance vision was similar with both types of lens implantation, near vision was better with multifocal IOLs, and intermediate vision appeared to be better in the monovision group...

BACKGROUND: Some pseudophakic patients implanted with a monofocal intraocular lens (IOL) have good near visual acuity (VA) with their distance correction. The objective was to evaluate the prevalence of pseudo-accommodation in children after bilateral cataract surgery, without amblyopia, and to define its mechanisms. METHODS: Observational study that took place in a pediatric ophthalmology department, Paris, France. A total of 68 eyes were included, 40 from 23 children and 28 from 14 adults, with a corrected distance VA above 20/25 and a normal near VA (20/25) with +3 addition...

: We report the first experience with presbyopia correcting femtosecond laser surgical procedure INTRACOR. This procedure is so far the only one that is made purely intrastromally without generating a wound connected to corneal surface or anterior chamber.Presbyopia - caused by physiological aging and decreasing elasticity of the lens, impairs patients accommodative ability. In the case of the method INTRACOR, presbyopia is corrected by steepening of corneal curvature in the central optical zone...
