Is it normal for eye vision to worsen a few weeks after corneal transplant surgery?

Yes: Depending on the type of transplant - full thickness or endothelial graft the tissues have to heal and stabilize. Please be patient with corneal grafting results - it takes a long time.

Depends: The uncorrected vision after corneal transplantation surgery will vary depending on many factors including healing of the corneal surface, decreasing corneal edema, decreasing ocular inflammation, scarring and healing of the transplant incisions. The final prescription can change as these things happen. Also infections and rejections of the cornea can also cause worsening vision.

Could happen: Any time the vision is changing, you should be checked out for rejection or infection issues. The vision can worsen depending on the astigmatism and amount of corneal swelling.

Yes: I see this most commonly in keratoconus grafts where initial swelling causes graft flattening. As the swelling goes down the graft steepens and becomes more myopic. Of course any transplant can have a change in refractive error and astigmatism as it heals. I would not worry about rejection this early but if there is any pain or increase in redness or light sensitivity i would see your surgeon now.

Maybe: It is common for vision after corneal transplant surgery to fluctuate and the uncorrected vision may be decreased as compared to prior to surgery. It may be 6-12 months before you will be to your best vision.
