Corneal Transplants; What Are They

Penetrating Keratoplasty (PK)
This type of cornea transplant replaces the full thickness of the cornea with a healthy and clear donor tissue and is required when a cornea has been severely damaged or disease, and where no other option of surgery remains. PK can be carried out under local or general anaesthetic and takes about one to two hours to complete. During surgery, a central 8mm button of cornea is removed and a similar sized button of the donor cornea is stitched in with tiny stitches. After surgery vision will stay misty and/or cloudy for a few days and will improve gradually for about 12-18 months. Individual stitches may be removed from three months after the surgery, but complete stitch removal is not performed until at least one year after the surgery. Following surgery, and once fully healed, around 75% of transplant recipients have adequate vision to drive legally, but to get the best results from vision, glasses or contact lenses may need to be worn.

Deep Anterior Lamellar Keratoplasty (DALK)
This type of cornea transplant is a partial thickness transplant and replaces the front 99% of the cornea with a donor cornea. Unlike penetrating keratoplasty, DALK keeps the back layers of the cornea, the Descemet’s membrane and endothelium layer, in place and it is used as an alternative to PK, when these back layers of the cornea are healthy. The surgery itself is carried out much the same as PK, but just less donor cornea is used. Again, stiches are used to keep the donor tissue in place, but as only part of the cornea has been replaced, healing and visual recovery are usually quicker than what are seen with PK. To get the best vision following surgery, glasses or contact lenses may need to be worn.

Endothelial Keratoplasty (EK)
This type of cornea transplant is a partial thickness transplant and replaces only the back layers of the cornea. Unlike to above two transplants, EK can be further split into two methods; Descemet’s stripping endothelial keratoplasty (DSEK) and Descemet’s membrane endothelial Keratoplasty (DMEK). Both DSEK and DMEK are very similar and the procedure to carry them out is the same, but DMEK differs as the donor cornea tissue does not include any stromal layer tissue. The consultant ophthalmic surgeon will decide which surgery is necessary, depending on the damage or disease that is present. EK transplants are used when there is a problem at the back of the cornea. To help keep the cornea clear, the cells lining the inside of the cornea pump fluid to stop the cornea from swelling, if there are not enough cells, due to disease or damage, then the cornea starts to swell and vision will become cloudy. The surgery is carried out differently when compared to PK and DALK; it will again be under either local or general anaesthetic but a very small incision is made between the coloured and white part of the eye. The eye surgeon removes the dysfunctional endothelial cells through this opening and a disc of donor cells is placed back inside the eye. The donor endothelial cells are pressed to the back of the cornea with an air bubble and the patient will need to lie still for about 1 hour following surgery to make sure the air bubble stays in place. Occasionally, a few stitches to close the incision may be needed. Vision will stay misty or cloudy for a few days, and will get better over 3-4 months, as with all types of corneal transplants glasses or contact lenses may be needed after surgery to get the best results from vision

Computer Eye Strain & Meibomian Gland Dysfunction

Computer eye strain is caused when you overuse your eyes and they become fatigued. Eye strain can occur when looking at a computer screen, or other device, for too long. Normally resting your eyes can help relieve the symptoms of computer eye strain. Symptoms of computer eye strain can include; headaches, difficulty focusing, dry eyes, watery eyes, eye discomfort, blurred vision, itchy eyes, and tired eyes.

Computer Eye Strain; How Does It Cause Meibomian Gland Dysfunction?

The meibomian glands are the tiny glands on the lower and upper eye lid margins that secrete oil, which when we blink, protection the surface of the eye. This oil helps keep the water element of your tears from drying out too quickly. Meibomian gland dysfunction (MGD) is a very common type of dry eye disease where the meibomian glands do not secrete enough oil or the quality of the oil is not good. Normally in MGD the glands get blocked and very little oil, if any, can get out and this causes the eye symptoms. Computer eye strain can cause MGD due to a reduction in blinking. Most people when using a computer or similar device do not blink as often as they should, this can be up to 60% less blinking than when not looking at a computer. If your blink rate is reduced, the oils will not be secreted as often which means the watery element in your tears evaporates quicker, drying out your eyes. Overtime this can cause the glands to block leading to meibomian gland dysfunction.

Treatment for Meibomian Gland Dysfunction

There are many different types of treatment that can help MGD sufferers and what suits one person may not suit another. If MGD has been linked to computer eye strain, then looking at the way you use a computer is a good place to start. Trying to reduce the time in front of a computer can be difficult, especially if you use a computer for work, but remembering to blink and keeping hydrated will help. Also try to follow the 20-20-20 rule; every 20 minutes’ look 20 feet away from your screen for 20 seconds. MGD sufferers will likely need to combine this with other at home’ treatments, such as heated eye masks, eye lid massaging, artificial tear drops, taking omega 3 supplements, and possibly taking other medication. There are other treatments that can be offered with an ophthalmologist or eye clinic that have great results in helping with MGD when used in conjunction with the at home’ treatments;

E-Eye Intense Regulated Pulsed Light (IRPL) The E-Eye device creates polychromatic pulsed light using the new IRPL (intense regulated pulsed light) technology. The E-Eye releases a flash of light that is made up of a pulse train, which is flashed on the treatment area (cheekbone and temple area around the eye). Within this treatment area nerve branches are located and these nerve branches are connected to meibomian gland nerves. When these nerve branches are flashed with the E-Eye (IRPL) it causes a stimulatory response within the meibomian glands and they start to resume secretion of the normal oil layer again and symptoms of eye dryness will disappear. Accordingly, it will be effective in 80% of patients affected by dry eye disease. From a single flash of IRPL it is possible to produce sub-flashes of varying intensities, this offers unparalleled therapeutic potentials, especially with the treatment of MGD, which is impossible with conventional IPL. The E-Eye emits a cold light’ and it is non-invasive, totally painless, and entirely harmless to the eyeball.

6 Newborn Baby Eye Problems

A lot of people think eye problems come with age, but there are many eye problems that newborn babies can have. Babies can develop eye problems for a variety of reasons such as from infections, present of problem at birth, or congenital eye problems, amongst other reasons. Here I will go through a few of these problems.

1. Childhood Cataracts

Childhood cataracts is a common eye problem. They can be congenital, developing before or soon after a baby is born, or they can develop in older babies and children. Although more commonly found in older adults cataracts can happen at any age. Cataracts happen when the lens of the eye becomes cloudy and hardens which causes issues with the vision. Cataracts in babies are normally picked up by healthcare professionals when they are carrying out checks on the baby. It may be necessary for the baby to have surgery to remove the cataracts. They can occur in one or both eyes.

2. Blocked Tear Ducts

Tears are drained from each eye from four tiny holes on the eyelid margins, two at the top and two at the bottom. Another common condition in babies is that one or more of the ducts may be blocked. This can cause eye infections and the baby might need antibiotics to clear up the infection. If the tear duct does not open naturally, then surgery with an ophthalmologist may be required, but most tear ducts do open up by themselves within the baby’s first year.

3. Ptosis

Again, ptosis is a problem seen a lot in older adults where one or both eyelids start to droop. This can also be found in newborn babies where one or both eyelids do not develop correctly. Surgery may be needed, as if it is left untreated it can cause a lazy eye later in the baby’s life.

4. Retinopathy of Prematurity

Babies that are premature can be born with underdeveloped eyes. It tends to be the blood vessels that transport blood to the retina that are not fully matured and need more time to grow. Once a baby is born, the inside of the eye could be damaged if these type of blood vessels do not grow as they should. Premature babies will be under constant monitoring and they will have an examination of their eyes to make sure the blood vessels have developed correctly, if they are not then treatment may be needed to prevent any more damage to the eye.

5. Eye Infections

Babies are exposed to whatever bacteria is found in the mother’s birth canal during labour, and this can cause eye infections. It isn’t uncommon for babies to contract conjunctivitis soon after birth, an antibiotic drop or ointment will clear this up. There are also various sexually transmitted infections which can be passed onto the baby during labour that cause eye infections.

6. Eye Defects

Newborn babies can be born with eye defects that can affect any part of the eye such as the cornea, lens, retina, eyelids, one eye being smaller than the other, and sometimes there is an abnormality or loss of vision that cannot be explained. If a baby is born with an eye defect it is known as a congenital condition, and depending on the type of defect it is, will depend if treatment or surgery is needed.

Eyes are such an important part of us and looking after them needs to start from birth. If you have any concerns about your newborn’s eyes, whether it be infection, disease or just something that doesn’t seem right it is extremely important to get it checked by an eye doctor as soon as possible to avoid any long term damage or vision loss.
