What to expect in PRK Laser Eye Surgery
The aim of PRK surgery is to remove the need to wear glasses or contact lenses completely.
In PRK surgery, the excimer laser reshapes the surface of the cornea with extreme precision.
- In myopia or short-sightedness, the excimer laser flattens the curvature.
- In hyperopia or long-sight by steepening the curvature.
Each pass of the laser removes only 10-microns (one, one-hundredth of a millimetre) of corneal tissue. After the surface layer is removed, the PRK laser goes on to reshape the underlying corneal stromal layer. This process takes approximately 30 seconds or so.
A clear contact lens is then placed over the eye to protect the cornea as the surface cells regrow. It is common that both eyes are treated on the same day.
After five days, the contact lenses are removed from the eyes. The patient’s vision continues to improve for some weeks after the PRK surgery. Most patients are able to resume normal activities in less than one week after their PRK laser eye surgery.
What to expect in Paediatric & Squint Surgery
Optilase consultations for paediatric and strabismus squint patients are performed in the consulting rooms at Mandurah Eye Centre. Consultations for paediatric and squints is expected to last approximately an hour as dilating drops are instilled.
If surgery is needed, it is performed in the theatres at Peel Health Campus. Children from the age of one and upwards can have surgery there, under the care of Paeditrically trained anaesthetists.
Strabismus or squint surgery in adults will often correct misalignments that developed in childhood that may not have been corrected or have worsened over time.
In adults, the preferred option is to correct the squint with an adjustable suture, either later the same day or the next day. The sutures can be adjusted or moved under local anaesthetic drops to get an exact correction.
