IPL:a new technology for painless treatment of dry eyes

2021-11-29 News

We often say that medicine has its limitations, but the pursuit of scientific progress has never stopped. In 2017, the Third Hospital of Peking University introduced a number of new medical technologies. After strict approval and long-term observation, they have now turned to the popularization and application of conventional technologies. These new technologies bring new hope to many patients. Let's see what these technologies are.

IPL:a new technology for painless treatment of dry eyes

First, let's talk about a patient's treatment experience

Dry eye has become one of the common diseases that interfere with modern people's life. From students, young and middle-aged workers, menopause to the elderly, there are many people suffering from dry eye, of which more than half of dry eye symptoms come from meibomian gland dysfunction.

The first time I saw Mr. Sun, he had been in many hospitals in China and had been suffering from dry eye for three years. At the age of 32, he has become an IT elite, working in a top software company in China. It may be that this kind of high-intensity computer work made him suffer from severe dry eye, which was the most serious patient I had ever seen.

Because of the obvious eye pain caused by dry eye, he could not open his eyes and could not stand any light stimulation. Mr. Sun could not live a normal life, and there was no way to talk about his work.

When he saw Mr. Sun, he wore a pair of sunglasses, wrapped wet gauze around the sunglasses, and wore a sun hat. He almost walked with his eyes closed. With all kinds of eyedrops in hand, I really need to drop a few drops when I open my eyes. Every time I open my eyes, I cry because of the pain.

Now the only treatment that can make him feel comfortable is meibomian gland massage, which can relieve him for about a week after each massage. However, due to the pain of meibomian gland massage, he could not do it too frequently, and massage once every two weeks.

In Mr. Sun's examination, it was found that his meibomian gland had been blocked for a long time due to intensive eye work, and keratinization and glandular function degradation had occurred. Long term dry eye disease led to continuous defect of his corneal epithelium. No wonder he could not open his eyes to fear light. Mr. Sun has tried almost all dry eye treatments, but the effects are not ideal. When I came to the Third Hospital of Beijing Medical University, it happened that the new technology of intense pulsed light (IPL) for the treatment of dry eye had just been approved, so I used this treatment technology with the consent of Mr. Sun. The treatment equipment used was the MDC Eyesis strong pulsed light dry eye therapeutic instrument using the fourth generation MOPT technology.

Considering that Mr. Sun's meibomian gland dysfunction is too serious, and the disease lasts for a long time, and the disease is stubborn, plus the intense pulsed light (IPL) treatment is not painful, we will treat it once a week. Surprisingly, after three times of treatment, Mr. Sun has felt better and can at least open his eyes normally. Eye examination showed that the cornea was much better. Make persistent efforts. After two courses of treatment, Mr. Sun's eyes have basically recovered.

At present, Mr. Sun has been able to work normally. In view of our suggestions, he has transferred from the research and development department to the management department. With the careful care of everyone, his eyes have been kept in a good state.

Why does intense pulsed light (IPL) cure dry eyes?

The tear film on the eye surface is the most important component to maintain the normal environment, comfort and lubrication of the eye surface. The balance and stability of water, protein, ester and other components in tear film is the key to ensure that tear film is intact and reflects its role. In particular, esters are the most important factor to maintain the stability of tear film, but they are also vulnerable to the impact of various ocular surface diseases. As a result, the tear film is unstable, causing dry eyes and other ocular surface discomfort.

The dysfunction of meibomian gland destroys the secretory function of meibomian gland, which is the main cause of dry eye in patients of all ages. The basic pathological process is that the normal secretion of esters from the meibomian gland decreases or the secretion changes due to changes in the eye use environment or hormone levels in the body, causing damage to the tear film environment on the eye surface and even breeding of bacteria.

The MDC EYESIS intense pulse light dry eye therapeutic instrument is used to treat the dysfunction of the meibomian gland. It uses 580~1200nm pulsed light waves to directly act on the meibomian gland gland, generate heat effect and related therapeutic effects, improve the properties of secretions and esters, dredge the blocked meibomian gland gland, so as to promote the supply of normal ester components required by the tear film, and promote the normal secretion of the gland and the recovery of meibomian gland function.

Continuous intense pulsed light (IPL) treatment can improve the secretion function of the meibomian gland, improve the quality of tear film, and gradually recover the ocular surface microenvironment.

What is the difference between intense pulsed light (IPL) and traditional treatment?

The traditional treatment for meibomian gland dysfunction is meibomian gland massage and hot compress. The duration is short, does not change the secretion character, and the massage process is painful.

The intense pulsed light (IPL) is used for painless, mild and comfortable treatment. Intense pulsed light (IPL) treatment adopts infrared deep hot compress, which is more thorough than traditional hot compress, and can effectively improve the characteristics of meibomian gland secretion and dredge the gland.

The effect of this treatment lasts for a long time, and the effect can be maintained for six months to one year after four treatments.

What patients is the new technology of intense pulsed light (IPL) suitable for?

Patients with meibomian gland dysfunction;

Dry eye patients with poor tear quality;

Patients with palpebral margin change due to blockage of meibomian gland;

Most middle-aged and elderly dry eye patients without ocular surface infectious diseases;

Video terminal type dry eye.


Intense pulsed light (IPL) has a significant effect on the treatment of dry eyes with meibomian gland dysfunction. A course of treatment (four times) can significantly improve the symptoms of such patients. The treatment process is convenient and painless, and the effect lasts for a long time, lasting from half a year to one year. It is currently recommended as a painless treatment for dry eye.
