Pterygium and Lasik eye Surgery
Pterygium, which is a callus, is a result of dry eye. Lasik can further increase the dryness of eyes. Hence, Lasik eye surgery may cause progression of Pterygium. Depending on the decision of the surgeon Lasik eye surgery should be avoided in the presence of Pterygium.
There are several reasons why Lasik may be deemed unsafe if you have Pterygium:
- During the process of making the Lasik flap the head of the Pterygium may get cut. This is a big problem for the patient. For an irritated Pterygium is worse for the eye.
- Second the Pterygium may go grow into the interface causing visual problems. Since the potential space allows it an unimpeded progress it may expand in all directions lifting the flap. This results in irregular astigmatism causing ghosting of images.
- Thirdly the progressive Pterygium may grow over the flap. Removing it may be very difficult, as it may lift the flap.
- Lastly the Pterygium may grow over and under the flap and this will affect the nutrition of the flap leading to the destruction of the edges of the flap.
So what are the options to see better in the presence of Pterygium?
- Superlasik eye surgery is a great option for people suffering with pterygium. It avoids entering into the cornea. It can avoid disturbing the flap.
- Another option is Visian ICL: Implantable collamer lenses inserted away from the pterygium
- The best option is Superlasik eye surgery combined with Pterygium removal. Superlasik as you may recall, uses a highly specialized automated instrument called epikeratome. This separates the top layer of the cornea along a natural cleavage plane. The same plane is required to separate the progressive pterygium.
Therefore combining the two procedures makes a lot of sense. It does require advanced instrumentation and higher skill. But this is likely the best option to tackle two problems at once. Also since both procedures require similar medications it saves time and money for the eye drops. And it will decrease the total number of visits to the lasik eye surgeon.
