Frequently asked questions
Every answer, in one place
44 questions patients ask before an evaluation or surgery with Dr. Serrano, answered without promising an outcome. Anything that depends on your eye is decided at the evaluation.
The clinic and appointments
Where is the clinic? Do you see patients from Cabo San Lucas?
At Paseo de los Marinos 635, San José del Cabo, ten minutes from the hotel zone and the airport and 30 to 40 minutes from Cabo San Lucas along the corridor. We see residents and visitors from all of Los Cabos; a large share of patients come from Cabo San Lucas.
How do I know if I'm a candidate for surgery?
Your prescription gives a first indication, but the decision depends on the shape and thickness of your cornea, your age, how stable your prescription is and your eye health. That's why we ask for a recent exam and Dr. Serrano reviews it with you by video before anything is booked.
I live in the U.S. How does this work?
First a video evaluation from home. If you're a candidate, we build the plan with you: dates, how many nights in Cabo, hotel and transfers. You have surgery here, Dr. Serrano checks you the next day and clears you to fly, and later check-ups are coordinated with your own optometrist in your city.
How much does it cost?
It depends on the procedure and, for lens surgery, on the intraocular lens chosen. We publish reference prices in U.S. dollars on the cost page and give you a written quote after your evaluation.
Who operates and who does the follow-up?
Dr. Antonio Serrano Hernández, in every case. The evaluation, the surgery and the next-day check are all done by him personally.
What if I arrive and turn out not to be a candidate?
That is exactly the scenario the video evaluation and the prior exam are designed to prevent. If Dr. Serrano nonetheless decides not to operate at the in-person check, your deposit is refunded.
Lens exchange
Is this the same as cataract surgery?
Technically yes: the natural lens is removed and an intraocular lens is placed. The difference is the reason — here it's done to correct your prescription and presbyopia, not because the lens has clouded.
Are both eyes done on the same day?
That depends on the plan Dr. Serrano sets for you. He explains it at your evaluation, along with how many days you'll need in Cabo.
How soon after can I fly?
Only after your in-person check and written clearance from Dr. Serrano. The trip is planned around that, not the other way round.
Lens exchange or LASIK after 45?
LASIK reshapes the cornea but leaves a lens that is already losing its focus and will later cloud. Lens exchange addresses the lens itself, so it can help with distance and near together and removes the future cataract. It is also surgery inside the eye, with different risks. The evaluation weighs both for your eyes.
Monofocal, toric or multifocal lens: what is the difference?
A monofocal lens gives its best focus at one distance, usually far, with reading glasses for near. A toric lens also corrects astigmatism. Multifocal and extended-range lenses spread focus across distances and reduce the need for glasses, with a higher chance of halos at night. The choice changes the price and is made before you book.
Will I still need glasses after lens exchange?
Many people use glasses much less, but nobody can promise none at all. It depends on the lens chosen, on your eye's healing and on how demanding your near work is.
Does insurance cover refractive lens exchange?
When there is no cataract it is an elective procedure, and U.S. insurers generally do not cover it at home or abroad. You receive an itemised receipt you can use for a health savings or flexible spending account if your plan allows it.
Do you see patients from Cabo San Lucas and the corridor?
Yes; Los Cabos is one municipality and the clinic in San José del Cabo is 30 to 40 minutes from Cabo San Lucas. Lens exchange is done one eye at a time, so we plan the visits to keep the driving reasonable.
How do I know if I'm a candidate?
Your prescription gives a first idea, but the decision depends on corneal thickness and shape, a stable prescription and your eye health. That's why we ask for a recent exam and Dr. Serrano reviews it by video before you travel.
Does it hurt?
Anaesthetic drops are used. Pressure during the procedure and a gritty, stinging feeling for the first hours are normal.
How many days do I need in Cabo?
Usually three or four nights: arrive, surgery, next-day check, and fly home with Dr. Serrano's clearance.
Is it safe to have LASIK in Mexico?
Safety depends on the surgeon, the screening and the follow-up, not on the country. What to check anywhere: that the surgeon's licence numbers can be verified, that the surgeon who evaluates you is the one who operates, that topography and corneal thickness are measured before anything is confirmed, and that there is an in-person check the next day plus a written plan for home. Dr. Serrano's licences are published on this site.
How soon can I fly after LASIK?
After the next-day check and written clearance. Cabin pressure is not the concern; dry cabin air is, so you travel with lubricating drops and use them often. Trips are planned as three to four nights for that reason.
Can I have LASIK after 40 or 50?
Age alone does not rule it out if the eye is healthy. But from the mid-forties the natural lens stops focusing up close, which LASIK does not fix, and later it clouds into a cataract. That is why lens exchange is often the better discussion after about 45.
Does LASIK wear off?
The change to the cornea is permanent. The rest of the eye keeps ageing: presbyopia in the forties, cataract later. A small number of people regress slightly and may be offered an enhancement.
Where is LASIK done, and how far is it from Cabo San Lucas?
At Dr. Serrano's clinic in San José del Cabo, on Paseo de los Marinos: about 30 to 40 minutes from downtown Cabo San Lucas along the corridor, 20 to 25 from the corridor hotels and 15 from the airport. The exam, the surgery and the next-day check are all there.
Cataract surgery
When should a cataract be operated on?
When it affects your daily life — driving, reading, seeing faces — not simply because it shows up on an exam. Dr. Serrano works through that with you.
Can a cataract come back?
Not in that eye: the intraocular lens doesn't cloud. In some cases the capsule behind the lens clouds over time and is treated with a laser in the office.
How do I know it is time for cataract surgery?
When the cataract gets in the way of things you need or love to do, such as driving at night, reading or working, and new glasses no longer help. A cataract seen on an exam that does not bother you can be monitored.
Does Medicare cover cataract surgery in Mexico?
Generally no. Medicare does not normally pay for care received outside the United States, and most private plans treat it as out of network at best. Check your own policy. Patients who come to Cabo usually pay directly and receive an itemised receipt.
Can both eyes be done on the same trip?
Sometimes. Whether the eyes are done on consecutive days, a few days apart or on separate trips depends on your eyes and on the plan Dr. Serrano sets. He tells you at the video evaluation, before you book flights, so you know how many nights you need.
How soon can I fly after cataract surgery?
After the in-person check and written clearance. Flying itself does not harm a normal cataract operation. The reason to stay is the check-up, not the aeroplane.
I live in Cabo San Lucas. Where is cataract surgery done?
At the clinic in San José del Cabo, 30 to 40 minutes along the corridor. You should not drive yourself on surgery day or to the next-day check; we help you plan a taxi or ride, or a family member drives.
Pterygium
Is a pterygium cancer?
No. It is a benign growth of the conjunctiva. It should still be examined by an ophthalmologist, because less common lesions can look similar and the removed tissue can be sent for analysis.
Can drops get rid of it?
Drops do not make it disappear. Lubricants, and a short course of anti-inflammatory drops during a flare-up, ease the redness and irritation. Removing it takes surgery.
What is the difference between a pterygium and a pinguecula?
Both come from sun and dryness. A pinguecula is a yellowish bump that stays on the white of the eye. A pterygium is a fleshy wedge with blood vessels that grows onto the cornea. A pinguecula rarely needs more than lubricants and sunglasses.
Will a pterygium grow back after surgery?
It can. The chance is much higher when the growth is simply cut away, which is why Dr. Serrano always covers the area with a graft. It still rises with sun exposure and with stopping the drops early. He tells you your own risk at the evaluation.
Are there stitches, and do they have to come out?
The graft is held with tissue glue and fine sutures. The glue reduces how much suturing is needed and tends to be more comfortable in the first days. Whether any sutures need removing, and when, is confirmed at your follow-up.
How can I stop a pterygium from growing?
Wraparound sunglasses with UV protection, a brimmed hat, and lubricating drops in wind and dust. This does not shrink it, but it slows it and keeps the eye comfortable.
Can I have pterygium surgery while visiting Los Cabos?
Yes, but plan the follow-up. The drops continue for several weeks and are part of preventing regrowth, so it suits residents and long-stay visitors best. Visitors on a short trip should arrange checks with an eye doctor at home.
I live in Cabo San Lucas. Where is the surgery done?
At Dr. Serrano's clinic in San José del Cabo, 30 to 40 minutes along the corridor. The evaluation, the surgery and the next-day check all happen there; the later checks can be spaced to limit trips.
Glasses & contacts
How often should I have my eyes checked?
At least once a year, even if you notice no change: many conditions have no symptoms at first.
If you are visiting Los Cabos
Do you speak English?
Yes. Dr. Serrano and the front desk see patients in English and Spanish, and messages on WhatsApp are answered in English.
How far is the clinic from Cabo San Lucas?
About 33 kilometres (20 miles) along the corridor highway, usually 30 to 40 minutes by taxi or ride app depending on traffic. From the corridor hotels it is 20 to 25 minutes; from the San José hotel zone about ten.
Can I use my U.S. health or travel insurance?
We don't bill insurers directly. You pay at the clinic by card or cash and receive an itemised receipt and, if you need it, a written report. Many travel policies and some U.S. plans reimburse out-of-network urgent care abroad; check yours.
What if it's after hours or Sunday?
Message WhatsApp anyway; we answer when the clinic opens and fit urgent cases in first. For sudden vision loss, a chemical splash or a penetrating injury, go to the nearest hospital emergency room without waiting for us.
I'm an expat living here. Can Dr. Serrano be my regular eye doctor?
Yes. Residents come for annual exams, glasses and contact lenses, pterygium and dry-eye care, and cataract surgery when the time comes. Care is continuous, in your language.
Do I need an appointment?
Please message first so we can give you a time and avoid a wait. Walk-ins are seen when the schedule allows.
