Cataract · Refractive Surgery · Glaucoma

Expert eye care combining cutting-edge technology with personalized treatment

I am Francisco Abellán, an ophthalmologist trained at Hospital Universitario de La Princesa in Madrid. My clinical practice focuses on the diagnosis and treatment of glaucoma, cataract surgery, and refractive surgery.

I see ophthalmology as a combination of diagnostic precision, clear communication, and honest decision-making. My goal is for every patient to understand their condition, know their options, and receive individualized care supported by modern diagnostic technology and sound clinical judgment.

Treatments & Procedures

I offer a comprehensive range of advanced ophthalmology treatments and procedures, tailored to each patient's unique needs. From minimally invasive laser treatments to complex surgical interventions, I use cutting-edge technology to deliver optimal outcomes.

State-of-the-art cataract surgery with premium intraocular lenses including toric (for astigmatism), multifocal, and extended depth of focus (EDOF) lenses. Personalized lens selection to maximize spectacle independence and visual quality.

Clear lens extraction with premium IOL implantation for patients over 45 seeking spectacle independence. Ideal for high refractive errors and early cataracts, this procedure corrects both distance and near vision simultaneously.

Quick, painless laser treatment for posterior capsule opacification (PCO) that can occur after cataract surgery. This procedure restores clear vision in minutes without incisions or anesthesia.

FAQ

Frequently Asked Questions

Clear answers to help you understand your eye health and our procedures.

No, laser refractive surgery is virtually painless. We use anesthetic eye drops to ensure your comfort during the procedure. You might feel some pressure, but no sharp pain. Most patients report a mild gritty sensation for a few hours afterward.

Recovery is typically very fast. Most patients notice improved vision within 24 hours. You can usually return to normal light activities the next day, though you will need to apply eye drops for a few weeks to prevent infection and help with healing. Strenuous activities and swimming should be avoided for about a week.

The right time is when the cataract begins to interfere with your daily activities (driving, reading, etc.). There is no need to wait for it to "mature" as was previously believed. With current technique, early intervention is safer and the recovery is faster.

Glaucoma often has no symptoms in its early stages. If you are over 40, have a family history of glaucoma, or have high eye pressure, you should have a comprehensive eye exam every 1 to 2 years. If you are diagnosed with glaucoma or are at high risk, your ophthalmologist will recommend more frequent follow-ups, typically every 3 to 6 months.

Keratoconus is a disease that causes progressive thinning and deformation of the cornea. We treat it primarily with Corneal Cross-Linking to stop its progression, and in some cases with intracorneal rings to improve vision.

High eye pressure does not always mean you have glaucoma, but it does require a thorough evaluation. In our practice, we perform an assessment with optical coherence tomography (OCT), visual field testing, and pachymetry to determine your actual risk. Based on the results, we decide whether to start treatment or schedule periodic monitoring.

Recovery after cataract surgery is fast. Most patients notice improved vision within the first 24 to 48 hours. You will need to apply eye drops for a few weeks and avoid physical exertion during the first week. A follow-up visit is scheduled the day after surgery to confirm everything is healing properly.

A general eye exam is recommended every two years. From age 40 onward, it is advisable to include intraocular pressure measurement and fundus evaluation, especially if there is a family history of glaucoma or high myopia.
