Can my vision get worse again after laser eye surgery? What is regression?
The term regression refers to the possibility that the eye gradually becomes out of focus again and requires glasses. The focus of the eye never remains constant throughout life.
Even patients who do not wear glasses will undergo fluctuations in their focus.
The glasses or contacts you had 5 years ago would be out of date now and will be different from the glasses or contacts you might need in 5 years’ time. However, it is probable that your vision will remain within the spectacle free zone for a very long time and perhaps forever. In the early days of laser corrective surgery regression was not uncommon. The latest lasers seem to have a more stable outcome although by definition very long-term data is not available yet. Nevertheless it appears that with the latest technology enhancements can be carried out many years later if required.
