Presbyopia, popularly known as “eyestrain,” is one of the most common eye problems in our society. Symptoms start to appear at the age of 40-45 and affect a significant percentage of the population. Dr Itziar Martínez Soroa, a specialist in refractive surgery, talks about its nature, consequences and treatment.
What is presbyopia or eyestrain?
Presbyopia is an eye disorder associated with age (from the forties onwards), which, due to changes in the elasticity of the eye lens, leads to the loss of the ability to focus sharply on close objects. This disorder worsens gradually, making daily activities, such as reading texts or checking your mobile phone, difficult, hence causing significant eye fatigue and the need to wear glasses for near vision. This situation exacerbates when it is associated with other refractive errors.
Is it possible to solve presbyopia permanently?
The final solution is to replace the defective lens with an intraocular lens that focuses at different distances, both near and far, i.e. a multifocal intraocular lens. At present, there are different lens models and features; thus, after a thorough assessment and depending on the circumstances of each patient, a professional specialising in presbyopia will guide you on the suitability of the type of lens to be implanted.
What is the presbyopia surgery procedure like?
Lens surgery, also known as refractive lensectomy, is performed under topical anaesthesia (drops). An incision of just two millimetres is made in the eye, in the cornea, the interior contents of the lens are aspirated by phacoemulsification and the intraocular lens is implanted in the same place. The procedure takes approximately 15 minutes per eye and is performed on an outpatient basis.
Can all patients undergo presbyopia surgery?
Not all presbyopia patients are eligible for this surgery. It is essential to carry out an extensive diagnosis with cutting-edge technology, in order to assess the suitability of the procedure and to know the patient’s specific visual needs. Only in this way can we establish a customised treatment for each case.
Which technological advances would you highlight in presbyopia surgery?
Eye surgeries are becoming less invasive and safer. In eyes with special anatomical features, we value the combination with femtosecond laser technology, which replaces some manual manoeuvres and increases the precision of the procedure. However, it is in the field of intraocular lenses where technology has advanced the most, with the possibility of using lenses with different focus ranges, which allow us to adjust to the needs of each patient.
What is the postoperative period for presbyopia surgery like?
The postoperative period for this type of surgery is highly comfortable. In a few days, you can resume your daily activities. For the first month, it is advisable to avoid lifting weights, doing strenuous sport or wearing eye make-up. Eye drops containing antibiotics and anti-inflammatories should be applied to the eyes during this time.
Why do you recommend Miranza centres for this surgery?
At our centres, we combine eye care and state-of-the-art technology. The possibility of networking within the Miranza group allows us to participate in research projects and to be at the forefront of technology and innovation. However, I would especially highlight our team of opticians/optometrists, nurses and, very importantly, ophthalmologists, who are highly specialised in specific areas and boast extensive experience in performing diagnostic tests and cutting-edge surgeries. All this to ensure the best care and solution for each patient.
