Cataract: surgery, prevention and systemic medicine

How cataract surgery works, which lifestyle factors may play a role, and how the eye can reflect the body’s metabolic and oxidative status.

What cataract is and what it “tells”

Cataract is the progressive clouding of the crystalline lens, the eye’s natural lens. It is very common with age, but can appear earlier in the presence of systemic factors such as diabetes, smoking, intense sun exposure, long‑term use of certain drugs and metabolic imbalance. From a systemic ophthalmology perspective, cataract is viewed not only as a local eye problem, but also as a possible “signal” of oxidative stress and dysmetabolism, without replacing conventional medical explanations and treatments.

Vision that becomes slowly and progressively blurred.

Colors appearing duller or more yellowish.

Increased light sensitivity and glare, especially at night.

Lifestyle, metabolism and systemic medicine

When the lens is already markedly opaque, surgery is the only recognized definitive treatment. “Natural” remedies, eye drops or supplements cannot make an established cataract lens clear again. Systemic medicine, however, suggests considering cataract as one of the signs of an internal terrain characterized by oxidative stress, glucose dysmetabolism and connective tissue fragility. This is a theoretical interpretative framework, consistent with known risk factors, which is not in conflict with conventional medicine and does not replace guidelines or surgical protocols.

Within this framework, several lifestyle measures are discussed as support for both ocular and general prevention:

Glycaemic control and “dysmetabolic phenotype”

Good blood sugar control (balanced diet, proper diabetes management, regular physical activity) helps reduce glycation of lens proteins, one of the mechanisms studied in cataract associated with metabolic disorders. In systemic medicine this is framed within a “dysmetabolic phenotype”, where elevated glucose and insulin, together with low‑grade inflammation, contribute both to vascular risk and to earlier onset of cataract.

Smoking, oxidative stress and “oxidative phenotype”

Cigarette smoking increases oxidative stress at both ocular and systemic level and is associated with a higher risk of cataract. Quitting smoking is a recommendation shared by all scientific societies. In systemic terminology, a picture dominated by free radicals and reduced antioxidant defences is described as an “oxidative phenotype”: an interpretative label that complements, without replacing, traditional risk‑factor categories.

UV protection and “connective matrix”

Consistent use of sunglasses with proper filters and wide‑brimmed hats reduces lens exposure to UV radiation, a major environmental factor in cataract development. From a systemic point of view, cornea, lens, vitreous and skin are seen as parts of the same “connective matrix”, influenced by light, lifestyle and ageing. Taking care of the skin and supporting connective tissues means, in parallel, protecting ocular structures as well.

Antioxidant diet and inflammatory “milieu”

A diet rich in colourful fruit and vegetables, whole grains, fish and healthy fats provides vitamins, carotenoids and other antioxidant compounds that help modulate oxidative stress. Systemic medicine interprets these choices as a way to improve the body’s low‑grade inflammatory “milieu”, in which eyes, vessels, brain and other organs are embedded.

Cataract surgery

Surgery is considered when cataract interferes with quality of life (driving, reading, work, safety) more than a simple refractive error would. There is no need to wait for a “mature cataract”: current recommendations suggest assessing surgery based on functional impairment and the patient’s needs. The systemic reading helps to place surgery within a broader vascular and metabolic prevention pathway, but does not change evidence‑based surgical indications.

In practice, patients are usually informed about a few key aspects of the procedure:

Duration: the operation usually takes only a few minutes per eye, in an outpatient setting.
Anaesthesia: in most cases, topical anaesthesia with drops is sufficient, without injections around the eye.
Sensations: during surgery patients perceive bright light and sometimes mild pressure, but not real pain.
Recovery: visual improvement generally starts within the first few days and stabilises over the following weeks, unless otherwise indicated by the ophthalmologist.

Post‑operative instructions

Specific instructions after surgery depend on the technique used, the operated eye and general health conditions. The rules listed here are examples of advice frequently given to patients and do not replace the personalised instruction sheet provided by the surgical centre.

Day of surgery

  • Stay at home and favour rest and gentle movements.
  • Do not remove the eye shield or patch until the surgical team tells you to.
  • Eat lightly, avoiding alcohol in the first hours after surgery.
  • If possible, avoid sleeping on the operated side during the first night.

First week

  • Eye drops: follow the prescribed schedule, dosage and duration accurately.
  • Hygiene: avoid getting water or soap directly into the operated eye; when washing hair, tilt your head backwards if needed.
  • Protection: wear sunglasses outdoors and, if advised, use a protective shield at night to prevent accidental rubbing.
  • Activity: avoid heavy lifting, intense sports or efforts that increase abdominal pressure.

First month

  • Environment: swimming pools, sea water, sauna, steam bath and very dusty places are usually discouraged until your ophthalmologist gives the all‑clear.
  • Cosmetics: eye make‑up on the eyelid margin or very close to the eye should be postponed until the surface is fully stable.
  • Sports: walking and light activity are often allowed; contact sports or high‑impact activities are evaluated on a case‑by‑case basis.
  • Driving: you may resume driving only when visual acuity is adequate and after explicit authorisation from your ophthalmologist.

Frequently asked questions

The artificial intraocular lens (IOL) does not develop a new cataract. Over time, however, the capsule holding it may become cloudy (“posterior capsule opacification”); in such cases, a brief outpatient YAG laser procedure is used to restore clarity.

Decisions about stopping or continuing medications such as antiplatelets or anticoagulants are always made jointly by the ophthalmologist, the GP and, when needed, the anaesthetist. In many cases these treatments do not need to be interrupted, but each situation is assessed individually.

The type of IOL (monofocal, toric, multifocal or EDOF) is selected based on ocular characteristics, visual habits and patient expectations. During the pre‑operative visit, pros and cons of the different options are discussed, including the possibility of leaving a small amount of “functional” myopia for near vision.
