Purpose: Subjects after cataract removal and intra-ocular lens (IOL) implantation lose their accommodation capability and are left with a monofocal visual system. The IOL refraction and the precision of the surgery determine the focal distance and amount of astigmatic aberrations. We present a design, simulations and experimental bench testing of a novel, non-diffractive, non-multifocal, extended depth of focus (EDOF) technology incorporated into an IOL that allows the subject to have astigmatic and chromatic aberrations-free continuous focusing ability from 35cm to infinity as well as increased tolerance to IOL decentration. Methods: The EDOF element was engraved on a surface of a monofocal rigid IOL as a series of shallow (less than one micron deep) concentric grooves around the optical axis. These grooves create an interference pattern extending the focus from a point to a length of about one mm providing a depth of focus of 3.00D (D stands for Diopters) with negligible loss of energy at any point of the focus while significantly reducing the astigmatic aberration of the eye and that generated during the IOL implantation. The EDOF IOL was tested on an optical bench simulating the eye model. In the experimental testing we have explored the characteristics of the obtained EDOF capability, the tolerance to astigmatic aberrations and decentration. Results: The performance of the proposed IOL was tested for pupil diameters of 2 to 5mm and for various spectral illuminations. The MTF charts demonstrate uniform performance of the lens for up to 3.00D at various illumination wavelengths and pupil diameters while preserving a continuous contrast of above 25% for spatial frequencies of up to 25 cycles/mm. Capability of correcting astigmatism of up to 1.00D was measured. Conclusions: The proposed EDOF IOL technology was tested by numerical simulations as well as experimentally characterized on an optical bench. The new lens is capable of solving presbyopia and astigmatism simultaneously by providing focus extension of 3.00D under various illumination conditions, wavelengths and pupil diameters of the implanted lens without loss of energy at any of the relevant distances.

Contrast sensitivity function (CSF) measures the overall sensitivity of the visual system from the retina to the visual cortex. There are numerous diseases, clinical and physiological conditions as well as aging processes that can influence the CSF. METHODS: The 22 subjects (8 male and 14 females) ranging in age from 19 to 75 years that participated in the study were divided into two groups - below and above 50 years of age. The older patients were all pseudophakic. All subjects underwent complete eye examination and were refracted and corrected for the trial's working distance of 1.5 meter. Scotopic CSF was tested monocularly after 3 minutes of dark adaptation by a computerized method using Gabor patches as targets with spatial frequencies between 1.5-6 cycles per degree (cpd). The test was conducted in a completely darkened room, with the monitor covered with neutral density filters having a luminance of 0.35 cd/m². RESULTS: The mean CSF for the older age group was 11.6, 10.3, 5.5, 2.9 for 1.5, 2.25, 3, 6 cpd respectively while the mean CSF for the younger age was 20.7, 9.8, 3.8, for the frequencies of 1.5, 3, 6 cpd respectively. Univariant analysis had found the association between CSF and both age group and spatial frequencies to be statistically significant (p=0.027, p<0.001 for age group and spatial frequency, respectively). A fair negative correlation between age and the dark-adapted contrast sensitivity was calculated (correlation coefficient=-0.35, p=0.004, adjusted for spatial frequency). CONCLUSION: CSF under nearly scotopic conditions declines with age, a decline that can only partially explained by preneuronal factors. In both age groups the CSF declines with increasing spatial frequency. In most of the older subjects the 6 cpd Gabor patches were too difficult to detect. This selective CSF loss may reflect either reduction in cone spacing, or decreased efficiency of neural processing from the fovea to the cortex. The fact that the younger subjects are sensitive to the higher spatial frequencies and the fact that the test was performed only after 3 minutes of adaptation, support our assumption that we are measuring a foveal function. The simplicity, duration and personal computer compatibility make the procedure practical and readily available for use in clinical settings.

Laser photocoagulation treatment of the central retina is often complicated by an immediate side effect of visual impairment, caused by the unavoidable laser-induced destruction of the normal tissue lying adjacent to the lesion and not affected directly by the laser beam. Furthermore, accidental laser injuries are at present untreatable. A neuroprotective therapy for salvaging the normal tissue might enhance the benefit obtained from treatment and allow safe perifoveal photocoagulation. We have developed a rat model for studying the efficacy of putative neuroprotective compounds in ameliorating laser-induced retinal damage. Four compounds were evaluated: the corticosteroid methylprednisolone, the glutamate-receptor blocker MK-801, the anti-oxidant enzyme superoxide dismutase, and the calcim-overload antagonist flunarizine. The study was carried out in two steps: in the first, the histopathological development of retinal laser injuries was studied. Argon laser lesions were inflicted in the retinas of 18 pigmented rats. The animals were sacrificed after 3, 20 or 60 days and their retinal lesions were evaluated under the light microscope. The laser injury mainly involved the outer layers of the retina, where it destroyed significant numbers of photoreceptor cells. Over time, evidence of two major histopathological processes was observed: traction of adjacent nomral retinal cells into the central area of the lesion forming an internal retinal bulging, and a retinal pigmented epithelial proliferative reaction associated with subretinal neovascularization and invations of the retinal lesion site by phagocytes. The neuroprotective effects of each of the four compounds were verified in a second step of the study. For each drug tested, 12 rats were irradiated wtih argon laser inflictions: six of them received the tested agent while the other six were treated with the corresponding vehicle. Twenty days after laser expsoure, the rats were sacrificed and their lesions were subjected to image-analysis morphometry. The extent of retianl damage was assessed by measuring the lesion diameter and the amount of photoreceptor cell loss in the outer nuclear layer. Methylprednisolone and MI-801 were shown to ameliorate laser-induced retinal damage, whereas both superoxide dismutase and flunarizine were ineffective. Furthermore, MK-801 diminished the proliferative reaction of the retinal pigment epithelial cells. On the basis of our results we suggest that the pigmented rat model is suitable for studying and screening various compounds for their neuroprotective efficacy in treating retinal laser injury. We further suggest that glutamate might play a key role in mediating retinal injury induced by laser irradiation.
