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

How To Prepare For Cataract Surgery

1) Glasses
If you are having both eyes treated it is likely both eyes with be done on separate days, roughly 1 week apart. This means once the first eye is treated, you will have a good eye and a bad eye, so you may struggle with your vision in this time. The best thing to do if you do find this difficult, is to ask your optician to remove the lens in your glasses for the eye that has been treated, they can leave it empty or they may be able to put in a prescription free lens.
You can also wear a contact lens in the untreated eye to help, but remember depending on the type of contact lenses you wear, these must be left out for a certain time before surgery, this can vary from 24 hours to 2-3 weeks, so it may be best to arrange for some glasses to have on standby.
2) Cleaning Your Eyes
You won’t be able to get water in your eyes for about 2 weeks following the surgeries, this is to avoid getting an infection. You may find your eyes get sticky from the prescribed drops you will be using after surgery, so you might want to clean your eyes. It is a good idea to buy what you need to do this before you have the surgery. You will need a clean bowl, cooled boiled water and some gauze. Boil the water and pour it into the clean bowl and let it cool. Once cooled you can soak the gauze in the water, ring it out and very gently wipe over the eyes and eyelashes, being very careful not to push on the eyes or drag the skin.
3) Eating
Most patients will be awake during cataract surgery and will have local anaesthetic to numb the eye, therefore it is advised to eat a good meal and keep well hydrated before you come to the clinic/hospital for surgery. If you are going to be put to sleep using general anaesthetic or be sedated, then you will not be able to eat or drink before surgery, this can vary from 6-12 hours beforehand. Your eye clinic should advise you on eating prior to surgery, but also ask them to confirm this if you are unsure or have not been advised.
4) Transport Home
After surgery, you will not be able to drive yourself home so you must arrange for someone to collect you, whether this be a family member or friend or a taxi. Ideally it wouldn’t be recommended you take public transport as you may struggle getting around on this. Also, you may not be able to drive for several days after the surgeries, so it is always best to have someone that can drive you around or it’s a good excuse to put your feet up and rest.
5) Sunglasses
So, it may not be a sunny day when you have surgery and it may even be night time when you leave the clinic/hospital, but we would recommend you bring a pair of sunglasses. Even though it is likely that your eye that has been treated on will be covered, either by gauze or a plastic shield, you may find lights brighter than normal, such as the sun, car lights and street lights. Also, the sunglasses act as another shield to protect your eyes from dust, wind or any other debris that could get in your eyes which could potentially cause an infection.
6) Time Off Work
If you work, you will need to prepare taking some time off after the surgeries. This can depend on the type of job you do but can vary from 2 days to 1 week after each eye has been treated. When you return to work, you may need to take extra caution depending on your environment, for example if you work in a dusty atmosphere you will need to wear protective goggles for several weeks to protect your eyes. Speak to your ophthalmologist about the type of work you do and they will give the best advice on returning to work.
All of the above is only a guide and your eye doctor may give different advice to you as every patient and surgery is different and recommendations will be tailored to suit your surgery, lifestyle, and needs. Remember if you have any questions about preparing for surgery, contact your eye clinic/hospital before the day of the surgery.
