Our Alternative Eye Surgery Options
Our 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.
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 and blur.
- 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, keratoconus 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.

Corneal Collage Cross-Linking Surgery
Corneal Collagen Cross-Linking surgery is used to prevent the progression of a corneal condition called Keratoconus. Here at the Wellington Eye Centre we perform Transepithelial Accelerated Corneal Collagen Cross-linking, this is a technique where the epithelium (the outer most layer of the cornea) is not removed.
Collagen cross-linking involves applying a b-vitamin solution to the eye to soak into the cornea and then exposing the cornea to UV light. This causes the collagen in the middle layer of the cornea (the stroma) to strengthen which can halt the weakening that occurs in progressive cases of keratoconus. Collagen Cross-Linking has been extensively researched and has a proven safety and effectiveness in halting Keratoconus progression.
At the Wellington Eye Centre, we have state of the art cross-linking equipment which means it is possible to customise the cross-linking treatment to your eye, treating the weaker parts of your cornea. To find out more contact the clinic and organise a consultation today.
Even after cross-linking treatment glasses and contact lenses may be needed to correct the vision.

Keraring Corneal Surgery
The Wellington Eye Centre also performs Keraring surgery to help improve the vision of keratoconic eyes. Kerarings are small plastic inserts that flatten the cornea and can help improve a patient’s vision.
To find out if you are suitable for kerarings, contact us and organise a consultation with our team today.
