Stereoacuity and Aniseikonia: Evaluation Before and After Bilateral Implantation of Three Types of Presbyopia-Correcting Intraocular Lenses in Uncomplicated Phacoemulsification with Due Consideration of Interocular Differences in Higher Order Aberrations, Axial Lengths, Refractive Errors, and Acuities.

Purpose: To determine if the changes in stereoacuity and aniseikonia, following bilateral implantation of presbyopia correcting intraocular lenses could be predicted from preoperative measurements of higher order aberrations (HOAs), axial lengths (AL), refractive errors (RE) and corrected visual acuities (CVAs).

Patients And Methods: Stereoacuity (Randot tests, @6m & 40cm, in steps of 20 arcsecs") vertical and horizontal aniseikonia (Awaya test @6m, in steps of 1%) with best correction and HOAs (Shack-Hartmann aberrometer) were measured before, 3 and 6 months after uncomplicated bilateral phacoemulsification. Twenty patients (I) underwent a mix-and-match procedure (Tecnis MF, ZKB00 in one eye and ZLB00 in the other), 17 (II) were implanted with a trifocal (AT LISA 839 triMP) and 18 (III) with a one-piece diffractive (Synergy OU) intraocular lens.

Different Surgical Approaches for Treatment of Dissociated Vertical Deviation (DVD).

Introduction: DVD is a rare, poorly understood eye motility disorder of unknown etiology. In socially unacceptable deviation, surgical treatment is an option. We present patients operated with three different surgical methods.

The clinical depth of field achievable with trifocal and monofocal intraocular lenses: theoretical considerations and proof of concept clinical results.

Background: To estimate the depth of field (DOF) achievable with multi-and monofocal intraocular lenses (IOLs) and compare with actual measurements of DOF in cases implanted with a trifocal IOL and biconvex monofocal IOL METHODS: I) Computer simulations were produced to describe the relationship between DOF, pupil size, preoperative ametropia, and retinal blur tolerance limit for a model eye implanted with either multi- or monofocal IOLs. II) Monocular DOF and pupil size were measured under distance viewing conditions between 3 and 6 months postoperative following uneventful cataract surgery. Cases were implanted with either i) trifocal aspheric IOL (n = 36), or ii) biconvex aspheric monofocal IOL (n = 26).

Resolution of pseudophakic cystoid macular edema with combination therapy of topical corticosteroids and nonsteroidal anti-inflammatory drugs.

A 69 years old women underwent uneventful cataract surgery of her left eye with phacoemulsification and posterior chamber intraocular lens implantation in topical anesthesia. Patient was postoperatively treated with combination of antibiotic and steroid in decreasing dosages during five weeks: one drop five times a day the first week, three times a day second to forth week and one time a day the fifth week. In each checkup, performed first postoperative day, 7 days, 5 weeks and 12 weeks after the operation, visual acuity with and without correction, tonometry, corneal transparency, biomicroscopy of posterior pole and measure of macular thickness by optical coherence tomography (OCT) were performed.

Amniotic membrane transplantation in the treatment of persistent epithelial defect on the corneal graft.

It has been shown that amniotic membrane transplantation (AMT) improves healing of the epithelium defects as it serves as a basement membrane for endothelial cells growth, prevents inflammatory cell infiltration and reduces apoptosis in keratocytes. Having in mind the healing properties of AM we investigated the efficacy of AMT in persistent epithelial defect (PED) on the corneal graft. 80 corneal grafts were prospectively followed up for presence of PED 10 months after surgery.

Comparison of different presbyopia treatments: refractive lens exchange with multifocal intraocular lens implantation versus LASIK monovision.

There are several methods for presbyopia treatment. Refractive lens exchange (RLE) followed by multifocal intraocular lens (MFIOL) implantation enables high rate of spectacle independence but have some visual disturbances. Laser in Situ Keratomileusis (LASIK) monovision gives patient ability to have good distant vision with dominant eye and good near vision with nondominant eye.

Penetrating keratoplasty and Verisyse iris-claw lens--is it safe for corneal graft?

The loss of the corneal endothelial cells, especially in a first postoperative year, has been observed in patients who underwent penetrating keratoplasty (PK). The implantation of new generation of "iris claw" phakic IOL (Verisyse) in refractive cases has been shown to cause clinicaly insignificant endothelial cell loss. In our prospective case series we investigated the endothelial cell loss and clinical outcome in patients that either underwent PK and implantation of PCIOL or PK and implantation of Verisyse IOL.

Comparison of diffractive and refractive multifocal intraocular lenses in presbyopia treatment.

Multifocal intraocular lenses (MFIOL) enable good near and far vision after cataract surgery. Excellent results with cataract patients encouraged ophthalmologists to implant MFIOL after clear lens extraction (CLE). There are two types of MFIOL: diffractive and refractive.

[Ten years of work of Lions Croatian Eye Bank].

Lions Croatian Eye Bank (LCEB) was founded in December 1995 under the leadership of Professor Nikica Gabric, to grow into the Reference Center for Corneal Transplantation of the Ministry of Health and Social Welfare of Republic of Croatia in 2001. The work of LCEB is coordinated according to the European and International Tissue Bank Association directives and laws (TBI). All donor tissues to be tested in the eye bank to ensure safe clinical usage.

Blue light filtering intraocular lenses in phacoemulsification cataract surgery.

Blue light can damage retina and cause age related macular degeneration. After cataract surgery and lens removal retina stays unprotected. Blue light filtering intraocular lenses (IOL) increase protection of the retina.

Sunshine on holidays--eye risks.

Ultraviolet (UV) light is the most common cause of radiation injury to the eye which in acute exposure causes photokeratitis and photoconjunctivitis. After a whole day exposure to the sun on the Mediteranian coast patient presented with mixed conjunctival injection, chemosis, edematous corneal epithelium with superficially present fluoresceine positive small pinpoint defects. Epithelial bullous changes, circular stromal infiltration in the middle stromal perifery and reduction of corneal transparency were more pronounced on the left eye.

Therapeutic efficacy of 5% NaCl hypertonic solution in patients with bullous keratopathy.

A clinical trial was undertaken to evaluate the efficacy of hypertonic solution (5% NaCl) in patients who have bullous keratopathy (BK). The aim of the study was to define the stage of the disease and the thickness of cornea in micrometers, which would be the threshold for therapeutic approach. This was a prospective study on 70 eyes of 55 patients.
