Our Alternative Eye Surgery Options
The Wellington Eye Centre’s experienced eye surgeons’ abilities to perform the most modern techniques make them some of the busiest and most in-demand eye surgeons in New Zealand. The surgery they perform includes corneal graft surgery, pterygium surgery and corneal collagen cross-linking to treat keratoconus.
Eye Disorders we Treat
A pterygium is a growth of thickened tissue that develops on the white part of the eye. It can affect your vision or cause redness and irritation if it grows large enough but not all pterygia need to be removed. You may want to remove a pterygium if:
- Your vision is threatened by the size of the pterygium.
- It’s causing grittiness, discomfort and redness.
- It’s causing astigmatism because of how its growth pulls on your cornea.
- You don’t like how it looks.
- You wear contact lenses and it’s interfering with how your lenses sit or if it’s irritated by the edge of the lens.
Pterygium surgery is usually performed using anaesthetic eye drops and takes 20-30 minutes. During surgery the pterygium is peeled off the cornea and the scar tissue is removed. This usually leaves a bare area on the white of the eye, which is covered by a skin graft taken from under the upper lid. Traditionally the graft has been sutured in place. However at the Wellington Eye Centre we use a natural tissue glue to stick the graft in place, to ensure a quicker recovery and less post-operative discomfort.
Corneal Graft Surgery
If your cornea has been scarred, distorted or damaged by infection or injury, our eye surgeons will perform corneal graft surgery to correct poor vision.
In traditional corneal grafting, the whole thickness of the cornea is replaced which causes slow visual recovery and healing, and astigmatism. Yet in many cases, only part of the thickness of the cornea needs to be replaced, which means faster recovery with less astigmatism, and less risk of the graft being rejected.
Dr Logan pioneered a technique known as DSAEK in New Zealand. In this operation, only a thin layer of cells on the back of the cornea is transplanted. This revolutionary technique offers fast visual recovery, especially in older patients.
