Halo effect after laser vision correction

Laser vision correction is one of the most commonly chosen methods for improving vision in people with refractive errors. Despite the high effectiveness and popularity of this procedure, some patients may experience some side effects. One of the most discussed and potentially troublesome problems is the halo effect after vision correction. In this article, we will try to give an overview of what the halo effect is, what causes it, and whether the halo effect passes and how it can be managed.

What is the halo effect?

The halo eye effect is an optical phenomenon that involves the perception of blurred, luminous circles around light sources such as streetlights, car headlights or lamps. Patients describe the effect as a halo or halo surrounding bright objects, which can significantly affect the quality of vision, especially in low-light conditions.

Causes of the halo effect after laser vision correction

The halo effect after vision correction can have various causes. One is a change in the shape of the cornea, which occurs as a result of procedures such as LASIK or PRK. During these procedures, the laser reshapes the cornea to correct the refractive defect. As a result, there may be some irregularities on the surface of the cornea, causing light scattering and creating a halo effect.

Another cause may be pupil size. In some patients, the pupil may dilate in the dark enough to exceed the limits of the laser-corrected area. As a result, the uncorrected corneal periphery can affect the way light enters the eye, leading to the appearance of a halo effect.

Halo effect after cataract surgery

Efekt halo może również występować po operacji cataracts, where intraocular lenses (IOLs) are implanted. Modern multifocal lenses, which allow both near and far vision, can in some cases cause haloing around light sources. This is due to the design of these lenses, which are divided into zones of different optical power. Although most patients adapt to this change, some may experience the halo effect for an extended period of time.

Is the halo effect going away?

Many patients wonder whether the halo effect passes after a certain period of time. In most cases, the phenomenon diminishes or disappears completely within a few weeks to a few months after surgery. The brain's adaptation to the new visual conditions and the healing process of the cornea play a key role in reducing the halo effect. However, in a small percentage of patients, the halo effect may persist longer and require additional interventions.

How do I remove the halo effect?

There are several methods that can help reduce or eliminate the halo effect. One approach is the use of special eye drops that narrow the pupil, thereby reducing exposure to uncorrected areas of the cornea. Another option is additional laser treatments, such as LASIK Enhancement, which can improve corneal irregularities and reduce halo.

For patients who experience a halo effect after cataract surgery, a change in intraocular lens type may be considered. Monofocal lenses, although they do not offer multifocal vision, usually do not cause halo. In some situations, the lens may need to be re-implanted.

Complexity of the issue and individual approach to the halo effect

Każdy przypadek efektu halo po laser vision correction jest inny i wymaga indywidualnego podejścia. Ważne jest, aby pacjenci, którzy doświadczają tego zjawiska, skonsultowali się ze swoim okulistą. Dokładne badanie oczu i szczegółowa ocena problemu są kluczowe dla wyboru odpowiedniej metody leczenia.

Laser vision correction is a complex procedure that, despite its high efficacy, can be associated with some side effects. The halo effect, although bothersome, usually diminishes over time and can be effectively treated. At the Blikpol clinic, we offer full support to patients both before and after the procedure to ensure the best possible results and a comfortable life.

Patient education and support

Educating patients about possible side effects, such as the halo effect, is crucial. Awareness of the risks and knowledge of methods to deal with potential problems allow patients to make informed decisions about their health. At Blikpol, we ensure that every patient is fully informed about all aspects of the procedure and has access to the best specialists and the latest technology.

Summary

The halo effect after laser vision correction is a phenomenon that can affect patients' quality of life, but with modern treatment methods and a personalised approach, it can be effectively reduced or eliminated. Understanding what the halo effect is, how it arises and what methods are available to treat it allows you to better prepare for the procedure and optimise the results. Blikpol Clinic offers comprehensive support and top-quality ophthalmic care, helping patients to achieve the best health outcomes.
