Halos and glare are symptoms of night vision that can be bothersome. This type of problem after laser eye surgery for myopia, hyperopia or astigmatism can be due to various reasons. Below we explain some of them, how we try to avoid them and how they can be solved.
Some patients may experience halos or glare after laser eye surgery. These are rings or flashes around lights in low light conditions. This type of visual problem can interfere with the ability to drive at night or at dusk.
In most cases this is a temporary side effect after laser eye surgery and disappears after a few weeks. If the problem persists, a series of tests should be carried out to determine whether it is possible to carry out a touch-up to solve the problem.
To alleviate the discomfort caused by halos or glare, the ophthalmologist may recommend the use of eye drops that reduce the size of the pupil (miotic eye drops) or night glasses to improve vision. Only in some cases is this a permanent complication.
How to avoid halos and night glare after laser eye surgery
Technology in refractive surgery is an important factor, as it is continually evolving to achieve better results. More than ten years ago, many ophthalmology clinics did not have the equipment to perform customised treatments. Today this is the norm, because it increases safety and reduces the risk of night vision symptoms.
Another essential aspect to avoid halos or glare after laser eye surgery is preoperative testing. A series of visual examinations that provide us with a great deal of information about the health and characteristics of the eye. For example: the corneal thickness, the degree of correction required, the size of the pupil, etc.
Based on the results, the ophthalmologist must assess whether there is sufficient corneal thickness to correct your degree of myopia, hyperopia or astigmatism with laser and how much grinding area you need. It is also important to take into account the size of the pupil, because if we limit the size of the optical area to be cut in the cornea according to the pupil size, we reduce the risks as much as possible1.
Customised treatments in Laser Eye Surgery
Customised treatments in Refractive Surgery are the best option. Because we individualise each treatment to ensure that each patient’s eye has the best possible vision. At the Vistaláser clinics in Málaga, Marbella and Granada we offer personalised femtosecond laser-assisted treatments that we plan taking into account the pupil at night.
As a result, we reduce the risk of higher order aberrations and achieve very high rates of satisfied clients. We are so confident in the effectiveness of our Femto Xtra treatments that we offer a Lifetime Guarantee. With this commitment, the patient will have the possibility to have a re-operation at no additional cost if their prescription changes after their laser eye surgery.
