Cataract is a condition causing clouding of the lens of our eyes that is responsible for focusing the images on nerve tissues located on our eyes’ back. Cataract in its advanced stage can result in dimmed vision and decreased visual clarity. The condition is usually treated by removing the clouded lenses. Majority of the cataract patients undergo a surgery in which the diseased lens get replaced by an artificial permanent lens called the intraocular lens. Intraocular lenses can be of different types; below, we have discussed about the 4 major types of intraocular lenses. Monofocal lens: Individuals choosing monofocal lenses during cataract surgery usually need contact lenses or glasses for providing correction of the visual distances located outside the implant’s fixed focus. If you have  [...] 

Nearsightedness can be defined as the vision condition marked by difficulty in seeing the objects far away clearly; however, a person with nearsightedness can see the objects close to him clearly. Below, we have discussed about the most effective homeopathic remedies for nearsightedness. Agaricus Muscarius: This homeopathic medication is prescribed when the patients feel that his eyes are pieced by ice needles and experience severe pain in the eyes. Some other signs indicating that Agaricus Muscarius will be effective in treating nearsightedness are: reading difficulty, delirium, fearlessness, vertigo due to sunlight, irregular heartbeat, coughing episodes accompanied by sneezing and swelling, redness, itching and burning sensation of the skin etc. Carboneum Sulphuratum: The signs that indicate  [...] 

Richard Taylor, a Univ. of Oregon scientist is endeavouring to develop flowers which could assist individuals with lost vision like those ailing from macular degeneration in seeing once more. These nanoflowers aren’t tulip, rose or columbine but generated from nano-size metal particles which are growing or self-assembling in an innate process – fractal growth or DLA (diffusion-limited aggregation). These would be fractals – (a trade-mark building-block of nature) which would be mimicking & communicating effectually with neurons. Fractal is defined as an object having uneven curvatures or forms, from which any single constituent when observed under-microscope too has the analogous form. An eye surgeon would be implanting such fractal device inside the eye of a sightless patient,  [...] 

Biodegradable implants are those not necessitating removal once objective has been achieved. OZURDEX biodegradable implants deploy superior NOVADUR medication delivery technology wherein a small rod-like implant is formed after merging active medication dexamethasone alongside biodegradable matter. Within the eyes, the vitreous gel filling it gradually dissolves these implants & releases dexamethasone. OZURDEX having the United States FDA approval are basically implants injectable inside the vitreous of the eye for treating adults having CRVO (central retinal vein occlusion) or macular edema after BRVO (branch retinal vein occlusion) & for treating adults having non-communicable uveitis afflicting the rear segment of the eye. OZURDEX has been established to be effectual in large-scaled  [...] 

A reasonably priced medication treatment excelled conventionally used laser method to fix a major reason of legally blind condition among preemies, as per a novel trial. Outcomes of the trial that appear in the latest edition of the ‘New England Journal of Medicine’ have that much significance that the fifteen hospitals partaking in the trial have halted the use of laser method and instead opting for the medication, Avastin that is administered in jab form into the eye areas of legally blind newborn babies. The Roche-make medicine is created for cancer treatment & the firm does not endorse its usage for any eye condition. Infants delivered prior to thirty weeks of pregnancy have eyes that haven’t matured & are at a greater risk of suffering from retinopathy of prematurity which  [...] 

Photorefractive keratectomy or PRK eye surgery is a laser eye operation for correcting slight to medium shortsightedness, hypermetropia &/or astigmatism. Basically, cornea (the translucent frontal portion of the eye that permits light passing via it) is reshaped in every laser vision rectification surgery. In PRK eye surgery, surgeons employ a laser beam delivering a pulsed shaft of UV light on the corneal surface instead of underneath it which is often the case with LASIK. Pros of PRK Eye Surgery It has high accuracy in rectifying several cases of shortsightedness. Around eighty percent of patients who undergo this procedure are able to get normal visual acuity post-procedure sans eye glasses or eye contacts. Twelve months post-procedure, ninety-five to ninety-eight percent of patients  [...] 

Physicians are testing laser therapy which could reinstate normal visual acuity among middle-aged people. Even as existent laser surgery can tackle nearsightedness, the novel method is capable of combating presbyopia (long sightedness) developing as a person ages. In case this turns out to be a success, it can radically lessen the cumbersome requirement of using reading glasses. On reaching fifty years of age, largely people come to the realization that reading menus, newspapers or books is not possible without being held at a distance. The decline arises due to lens of the eye developing stiffness thus finding it trickier to zoom in on closely placed items. Though using reading glasses is a widespread requirement, it is hardly ever welcome news for people succumbing to it and could deplete  [...] 

A small range of light sensitive diodes were able to restore an extent of eyesight to miniscule numbers of retinitis pigmentosa (RP) patients, a study scientist stated. The chip implantation within the retinal regions of 11 RP patients was done who were sightless for thirteen years to nearly four decades. No notable side-effects were observed among these patients according to spokesperson of the German maker of these devices, Retinal Implant AG of Tubingen, Mr. W. Wrobel who also demonstrated recordings that showed an entrant in the preliminary trial capable of recognizing letter, word types alongside identifying fruit forms according to shape and other entrants also exhibiting analogous favourable outcomes. RP is a condition arising due to progressive death of photoreceptors commencing at  [...] 

For around 1 in 10 people suffering from eye conditions like astigmatism and hyperopia, donning chunky eye glasses or at times contact lens throughout their lives are the sole options left. This complex combo of eye conditions is tricky in treating and there is greater likelihood of the therapy failing. Laser surgery has lesser efficacy since the eye is by their quite short. Though ophthalmologists could re-shape the corneal borders so that it could direct light beams in the direction of the retina with greater accuracy, however it appears to work solely for patients having mild hyperopia (or longsighted). In the last 4 years, doctors have managed to embed bendable mini contact lenses truly in the eye, in the room at the back of the iris & ahead of the eye’s innate lens for rectifying  [...] 

Several individuals in their forties opt for laser eye surgery to restore their focusing capability for near vision arising due to aging related alterations in the eye known as presbyopia. A novel ‘intra corneal’ or ‘within-the-cornea’ laser technique known as IntraCor has the potential to gain instant popularity as a presbyopia rectification surgical procedure. Although the procedure is still due to receive the FDA nod for usage in the United States, the method has exhibited favourable outcomes in European and S. American preliminary trials. The IntraCor procedure rectifies eyesight by the use of femtosecond laser for altering corneal curvature. The laser therapy is conducted totally inside the cornea sans the requirement for removing exterior corneal sheath (done in Photorefractive  [...]
