BACKGROUND Femtosecond-laser assisted clear cornea cataract surgery may hold promise in safer and more effective procedures. We decided to perform a comparative study to standard manual incision phacoemulsification surgery. METHODS This is a single-center, single-intervention, and prospective comparative data evaluation of 133 consecutive cases subjected to cataract surgery. Group-A (Phaco), ...

Case I.?Kakeel, Hindu, aged 40, admitted December 22nd, 1876, with double cataract. Both eyes were totally blind. On 23rd, the patient having been brought fully under the influence of chloroform, the operation of extraction was performed on the right eije, in the following way :?The lids having been opened by two assistants, an incision was made in the upper section of the cornea, a little in f...

PURPOSE To compare the consistency of incision architecture utilizing a traditional diamond keratome and a newly designed diamond keratome. METHODS We used a traditional diamond keratome and newly designed diamond keratome to create clear corneal incisions in human cadaveric donor eyes. Three surgeons with varying levels of experience made 30 incisions with each keratome; and the wound archit...

the incision is extremely small, such as a puncture with a needle or cataract knife, prolapse does not occur even if the lens diaphragm is destroyed. With very large incisions the use of a piece of catgut to prevent prolapse of the iris is unnecessary. Those who doubt this may conduct a few experiments on living animals. It will be found that if the cornea be completely excised under cocaine an...

PURPOSE The cornea is the major refractive component of the eye and serves as a barrier to the external environment. Understanding how the cornea responds to injury is important to developing therapies to treat vision disorders that affect the integrity and refractive properties of the cornea. Thus, investigation of the wound healing responses of the cornea to injury in a cost-effective animal ...

The case of a 40-year-old-man who presented to our clinic with bilateral blindness as a consequence of bomb blast injuries is reported. He had a completely opaque cornea, partially damaged posterior segment and perception of light in the right eye, while a clear cornea, totally damaged posterior segment and no light perception in the fellow eye. His corneas were successfully swapped which gave ...

introduction epithelial rejection typically begins in a linear pattern from the periphery of the graft and progresses centripetally. here in, we reported a patient with a new presentation of corneal epithelial graft rejection. case presentation a 23-year-old man presented with blurred vision two months after penetrating keratoplasty. conclusions slit lamp examination revealed sharply demarcated...

With the use of glass microelectrodes the electrical potential profile was determined in the isolated cornea of the frog, Rana catesbiana. The results indicate that the stroma of the cornea is ahvays negative (up to -32 mo.) with respect to both endothelial and epithelial bathing solutions. A model was developed that excluded the epithelium as the location of a previously described chloride pum...

Cornea is the most anterior segment of the eye that provides exquisite vision. This is transparent outermost surface of the eye, consisting of a stratified epithelium, a collagenous stroma and an innermost single-cell layered endothelium. Cornea is an important visual structure assists in providing a clear vision by refracting light onto the lens, which in turn focusing on the retina. It is a v...
