Cornea

Nepal’s Tilganga Institute of Ophthalmology has been working to build one of the most successful corneal donation programmes in the world.

A 110° reverse side cut primary incision created with a femtosecond laser provides an effective seal for potential wound leakage in a recent study.

Optimal planning for correction of pre-existing corneal astigmatism at the time of cataract surgery should take into account an age-related, against-the-rule (ATR) shift.

Patients with keratoconus pose unique challenges with IOL calculations.

Technique targets the main cause of vision degradation and a large clinical series finds positive results.

Watch as Ben Wucher, researcher at University of Rochester Medical Center, summarizes his research titled, "Clinical keratitis isolates of Pseudomonas aeruginosa develop resistant biofilms."

Early results from a repeatability and reproducibility study of a precision ultrasound device indicate the anterior segment imaging device can provide unique measurements on the cornea and will have multiple applications in the future.

Selective two-photon collagen crosslinking has been shown to stiffen any three-dimensional region inside corneal tissue without damaging surrounding tissues.

In this first of a two-part series, Arun C. Gulani, MD, MS, explains how approaching keratoconus as a refractive surgery will change the way both ophthalmologists and patients will approach this condition to bring in a new era of not only relieving but also enhancing the lifestyle of this patient population. In Part 2, Dr. Gulani will share strategies and cases of patients with keratoconus with different case scenarios in action.

Ganciclovir gel is effective for herpes simplex epithelial keratitis, and emerging evidence shows it also can be used to treat other corneal disease.

Post-keratoplasty fungal infections are becoming increasing more common, and the risk is significantly higher after DSEK compared with PK.

Acanthamoeba keratitis is a vision-threatening disease most frequently seen in contact lens wearers. The disease mimics numerous diseases, and early recognition is needed to achieve optimal visual outcomes.

Further calibrations for the equivalent keratometry readings (EKR) obtained by the Pentacam High Resolution (HR) (Oculus, Germany) should be conducted before they are used for total corneal power assessment in post-LASIK eyes, researchers said.

A new double-arc intrastromal corneal ring segment may help to improve visual outcomes and rehabilitate the physiologic optical surface by remodelling the cornea

Patients with dry eye can be kept healthy-and happy-by diagnosing properly, following specific treatment plans, and providing excellent communication.

Keratoconus in eyes with stage I or II disease has remained stable during follow-up to 2 years after circular keratotomy performed using a femtosecond laser.

Long-arc ICRS were developed to meet the needs of patients with nipple-type keratoconus. However, new study findings suggest they may also help to improve visual acuity and regularise the cornea in patients with all types of keratoconus.

Improvements in the Boston Keratoprosthesis device have resulted in fewer complications after implantation, but they still occur. Surgeons should be alert to development of infectious keratitis and endophthalmitis postoperatively.

Dr. Donaldson explains that prior corneal surgery does not necessarily indicate that FLACS would be ineffective. However, there are some immediate disqualifications to bear in mind.

One of the most memorable patients ever to walk into the office of Sonal Tuli, MD, had a fishhook protruding from his eye, which he held open with his fingers. Dr. Tuli offers some pointers based on experience from cases like these.

Endothelial keratoplasty has become increasingly common in northwestern Italy, paralleling a rise in the demand for corneal surgery, researchers said.

The same photoactivation process used in collagen cross-linking for keratoconus can kill bacteria without the need for the oxygen responsible for the biomechanical effects, potentially pointing toward better treatments for keratitis, according to Olivier Richoz, MD, PhD.

Topography disparity can even provide a useful parameter for diagnosing the subclinical form of the disease, said David P. Piñero, PhD, and colleagues from the Medimar International Hospital, Alicante, Spain.

When a graft fails, surgeons have three factors to consider: the reason for the graft failure, the chances of success with a second surgery, and what has to be done differently to ensure the success of a new graft, said Francis Price Jr., MD.

A 65-year-old male with a history of congenital cataracts, bilateral cataract extraction and secondary placement of anterior chamber intraocular lenses with subsequent development of glaucoma, cicatricial conjunctivitis, dry eye and limbal stem cell deficiency presented with left eye pain and decreased vision.
