A laser is then used to carefully reshape the cornea. The flap is set down again to heal. As your eyes are healing, it will take a while for your eyes to get used to the changes in vision quality and visual information. As a result, there may be glare or halos around objects that are brightly colored. In addition, patients are likely to experience issues with light sensitivity. Rest assured that these are all normal side effects and that they will resolve themselves in weeks after surgery as patients heal.
That said, it can be somewhat alarming to have to deal with these changes in overall vision quality. There may be fewer problems with glare and halos before that time, especially in the first week or so after surgery. Gradually with proper healing, these issues will pass. Other than halos, glare can also manifest in the form of starbursts, which, rather than being a ring around lights, appear more like a dispersed glow. In the first few weeks after Laser Eye Surgery , patients may also experience minor fluctuations in their quality of vision as it stabilises as well as dry eyes for which clinics provide lubricated eye drops.
In the vast majority of cases, all of these effects are mild and gradually disappear over the first few days or weeks. After around the three-month mark, swelling in the cornea will have settled along with any visual disturbances. It is possible for night glare and halos to persist long-term after laser refractive surgery.
This is most often related to a residual refractive error due to under or overcorrection — a small residual prescription or astigmatism can cause halos as well as blurred vision. However, as the eye is a biological system, an over or under correction can result from individual healing response relative to the average person.
Fortunately, the course of action is relatively straightforward — with many patients benefitting from having a simple follow-up procedure or wearing glasses at night. However, persistent night glare and halos can also occur even if the refractive outcome is perfect. Night vision symptoms were one of the major side effects of laser refractive surgery during the s with the first generation lasers.
These were caused by the shape of tissue that was removed by the laser and the area over which the shape change was performed. If the treated area was smaller than the pupil particularly at night where the pupil becomes larger , the edge of the treatment zone would cause halos around lights.
Over the last 20 years, there have been significant improvements made to the lasers and how to change the shape of the eye, so that a clinic with the right technology can minimize the risk of halos. The team here at Broberg Eye Care takes great care when treating patients. This is why we attract so many patients from throughout the greater Austin area.
They can count us to to perform a safe procedure and provide full information on the side effects of LASIK eye surgery. This combination of quality care and proper patient education goes a long way to ensuring optimal results. In general, issues with glare and halos tend to occur when looking at bright lights, shiny objects, or bright-colored objects. If you should notice varying degrees of glare and hols after LASIK, rest assured that this is normal.
During LASIK surgery, a flap is created in the topmost part of the cornea, which is known as the epithelium.
