Eye diseases are 50% more common in women 

Written by admin

Research by the IBGE (Brazilian Institute of Geography and Statistics) highlights the alarm signal for the eye health of the female population. The data reveals that difficulty seeing and loss of vision are 50% higher in them.

According to ophthalmologist Leôncio Queiroz Neto of the Penido Burnier Institute in Campinas, the research confirms an investigation carried out at the hospital a few years ago. For him, a woman’s greatest difficulty in seeing is a cascading effect of constant hormonal fluctuations that increase the production of free radicals in the eyes, and systemic diseases, such as diabetes and hypertension, more prevalent among them. .

Looking to the future

For women, all is not lost. The good news is that the winners of this March 8 place more importance on eye health. An ophthalmologist’s survey of 2,100 hospital records reveals that since the start of the pandemic, follow-up was 30% more regular among the 1,200 women in the group than among the 800 men. The bad news is that covid has increased the irregularity of eye monitoring by 65% ​​to 75% among those who have difficulty seeing.

For Queiroz Neto, the greater attention of women to their eyesight is associated with the psychological profile of the female population and the signaling of alterations such as myopia, difficulty seeing at a distance, which is 20% higher in women , since they spend more time working on the computer.

“The greater eye contact with the evaporation of cleaning products, cosmetics and make-up in the eye area also stimulates allergic processes,” he points out. This causes them to have 15% more astigmatism. “By dint of rubbing or scratching your eyes, the cornea, the outer lens of the eye, becomes irregular and forms multiple foci on the retina, leaving blurred vision both near and far,” he explains. he.


Myopia, astigmatism and farsightedness, difficulty seeing up close, can be corrected with glasses or contact lenses. Many do not adapt well to contact lenses and would like to say goodbye to glasses. One in two people spend most of their time without their glasses out of vanity. They therefore represent 2/3 of refractive surgeries, including during the pandemic which recorded a 7.5% drop in interventions.

For Queiroz Neto, the number of surgeries is not higher in Brazil because part of the population is afraid to operate. It’s clear, he reflects, that every procedure has risks and with refraction it’s no different. The biggest risk of surgery is contaminating the cornea. The specialist points out that the contamination occurs in 0.24% of the refractions carried out in the world. A meta-analysis carried out in the USA shows that wearing lenses for one year contaminates 3 times more and in 5 years the contamination is 7 times greater.

The procedure

In recent years, refractive therapy to correct myopia, hyperopia and astigmatism is one of the procedures that has added the most technology. There are 4 different techniques and they are all good. The most appropriate depends on the lifestyle, the thickness of the cornea, the intensity of the refractive error and the expectations of each patient, namely:

– Lens implant for the correction of high refractive errors: It is reversible and consists of implanting a lens between the iris and the lens without removing the lens. It allows the correction of up to 20 myopias, 10 hyperopias and 6 astigmatisms.

-Smile – Nanometer precision is all-laser surgery, from cutting to shaping the cornea. Therefore, it allows faster recovery, better healing and more postoperative comfort. The surgeon explains that the laser is applied point by point and removes 20% less tissue. Therefore, surgery can be performed on thinner corneas.

-Lasik – During the procedure, a manual cut is made in the outer layer of the cornea, to correct the refraction through the application of the laser in the intermediate layer and finish with the replacement of the cut lamella in the same place.

-PRK – This is a more traumatic procedure in which the laser removes cells from the epithelium, the outer layer of the cornea to model its shape with pulses of light. PRK has a slower recovery, but like all other techniques, it is painless. This is because all surgeries are performed with anesthetic eye drops.

dry eye

Neto says it’s normal to have dry eye after surgery because the laser changes the distribution of tears on the surface of the eye. To avoid any discomfort, each patient leaves the practice with a bottle of lubricating eye drops. From 1 to 3 months the eyes will recover, whatever the technique. This doesn’t mean they will never dry out again, but if it persists, a full eye lubrication assessment is needed. “Today the diagnosis and treatment are automated and allow the patient to visualize the improvement of the tear film and to adhere to the treatment”, he specifies. Those who are tired of using eye drops can feel comfort in their eyes again with just three IPL sessions.

If you plan to get rid of your glasses, you must be over 21 and have stabilized your prescription for one year. Pregnancy which makes refraction unstable, dry eye, glaucoma, thin cornea and retinal changes are contraindications. Therefore, it is important to go through a battery of tests and hope that the surgery is approved.
