For Singapore’s lorry and delivery drivers, the signs of cataracts are easy to dismiss. The consequences of waiting too long are not.
In Singapore, cataract surgery is one of the most commonly performed eye procedures. It is also one of the most delayed. For working drivers, the reasons for waiting are familiar: the shifts keep coming, the licence has not been flagged yet, and the changes in vision have been gradual enough to explain away.
Henry, 58, had driven a lorry across Singapore for thirty years. He knew the weight of a full load by feel, which expressway ramps to take before the morning rush, how to judge the gap between his vehicle and a kerb within centimetres. What he could no longer do, though he had spent two years refusing to admit it, was seeing the road the way he used to.
By the time he reversed out of the yard in Tuas each morning, oncoming headlights bloomed into halos wide enough to swallow the lane markings. Tail lights blurred into red smears. He had been slowing down, declining the overnight runs, leaning closer to the windscreen. His wife had noticed. His supervisor had noticed. Henry kept telling them the same thing: just tired. Long hours. Getting older.
He was not wrong about being older. But tiredness was not what was happening inside his eyes.
What Causes Cataracts, and When Is Cataract Surgery in Singapore Necessary?
Cataracts develop when proteins in the eye lens break down with age, UV exposure, or conditions such as diabetes, causing progressive clouding. This scatters incoming light rather than focusing it on the retina, producing blurred vision, glare, halos, and reduced contrast. Surgery replaces the clouded lens with a clear artificial implant in a short outpatient procedure. (Ang et al., 2018; National Eye Institute, 2023)
The lens inside the human eye is meant to be clear. Over time, accelerated by age, UV exposure, certain medications, and metabolic conditions such as diabetes, proteins within the lens begin to degrade and clump. The result is a clouding that cannot be corrected with glasses or contact lenses.
“What I often see in working adults,” says Dr Allan Fong, cataract surgeon at Angel Eye & Cataract Centre, “is that by the time they come to me, the cataract has been developing for two or three years. They adapted gradually. They did not notice how much they had lost until they could not ignore it.”
For drivers, the impact is disproportionate. Research published in Ophthalmology found that patients with cataracts experience significantly impaired contrast sensitivity under low-light conditions: the precise skill required to read road markings, judge distances, and respond to oncoming vehicles at night. (Owsley et al., 2002) For professional drivers, this matters beyond comfort. Singapore’s Land Transport Authority sets minimum visual acuity standards for vocational licence holders. When cataracts progress to the point where those standards can no longer be met, a licence is at risk. Cataract surgery in Singapore, performed as a day procedure under local anaesthesia, can restore visual acuity to the level required. After cataract surgery, Singapore-based patients typically resume driving within one to two weeks, subject to clearance from their cataract specialist.
How Do Cataracts Affect a Driver’s Ability to Work Safely?
Cataracts reduce contrast sensitivity and scatter incoming light, producing halos and glare around headlights and street lamps. A 2022 Annual Review of Vision Science confirmed that contrast sensitivity is a stronger predictor of night driving performance than visual acuity alone. Research shows 85.9% of people with cataracts in both eyes report difficulty driving after dark. (Wood, 2022; Owsley et al., 2020)
For Henry, the trouble was not just discomfort. In Singapore, commercial vehicle drivers must meet visual acuity standards set by the Traffic Police and the Land Transport Authority. A vocational licence is not merely a document. It is a livelihood that depends on your eyes meeting a measurable standard.
Research published in the British Journal of Ophthalmology found that cataract surgery significantly improved driving performance in patients who had previously been restricted by visual impairment, including reaction times and the ability to detect hazards under low-illumination conditions. (Wood et al., 2009) For working drivers, this is not an abstract finding. It is the difference between keeping a job and losing it.
This is the calculation Henry was running every morning on the way to Tuas, though he would not have called it that. He was just trying to make it through the shift.
What to watch for
- Halos or rings around oncoming headlights, especially at night
- Difficulty reading road signs clearly at a distance
- Glare from wet road surfaces or bright sunlight that feels overwhelming
- Needing to slow down or increase following distance because the road ahead looks unclear
- Avoiding driving at night or in rain without being able to explain why
Who Is Most at Risk of Work-Affecting Cataracts in Singapore?
Cataracts are most common in adults over 50, but risk rises significantly with diabetes, myopia, UV exposure, and steroid use. A Singapore-based cohort study found diabetes carries an odds ratio of 1.90 for requiring cataract surgery, with a population attributable risk of 17.6% among multi-ethnic Singaporeans. (British Journal of Ophthalmology, 2022; Singapore SEED Study)
Singapore sits just one degree north of the equator. UV radiation here is intense year-round, and years of exposure, driving a lorry with the window down, working outdoor routes without adequate eye protection, accelerates lens protein degradation. Cataract surgery Singapore ophthalmologists perform is disproportionately needed among long-term outdoor workers precisely for this reason. The World Health Organisation estimates that UV exposure accounts for approximately 20% of cataract cases globally. (WHO, 2023)
Diabetes is another significant risk factor, and Singapore has one of the highest rates of diabetes in Asia, with one in three Singaporeans at risk of developing it in their lifetime. (Ministry of Health Singapore, 2023) Diabetic patients are at substantially higher risk of early-onset cataracts, and the condition can progress more rapidly once it begins.
Henry had been managing Type 2 diabetes for six years. His GP had mentioned his eyes at every annual review. He had nodded, and he had not gone for the check-up.

What Happens to Your Vocational Licence If You Delay Cataract Treatment?
Untreated cataracts progress steadily. As the lens densifies, vision deteriorates until visual acuity standards for driving licences may no longer be met. Advanced cases, known as mature or white cataracts, can reduce vision to light perception only. The Singapore Epidemiology of Eye Diseases study found two-thirds of Singaporeans with visually significant cataracts were undiagnosed, with half experiencing bilateral visual impairment. (Soo Keat Khoo et al., 2017; SEED Study)
There is a common misconception that cataracts must be “ripe” before treatment, that patients should wait until the condition is severe before considering surgery. This is outdated thinking. Modern cataract surgery in Singapore is performed as a day procedure under local anaesthesia, and outcomes are significantly better when the lens has not been allowed to harden extensively. A dense, mature cataract requires more ultrasound energy to remove, slightly increasing the risk of complications. (Asbell et al., 2005)
For professional drivers, the timeline matters in another way. If visual acuity deteriorates below the standard required for a vocational licence before treatment is sought, there may be a period, even if temporary, during which a driver cannot legally work. The surgery itself takes minutes. Recovery to driving standard typically occurs within days to weeks, depending on individual healing. The gap between recognition and action is where livelihoods are lost.
Henry understood this, eventually. It was his wife who found the number of an eye specialist. It was his wife who made the appointment. Henry went because he had run out of reasons not to.

Frequently Asked Questions: Cataract Surgery Singapore Patients Want Answered
Can I still drive after cataract surgery in Singapore?
Most patients resume driving within one to two weeks of cataract surgery in Singapore, once their eye specialist confirms that visual acuity meets the required standard. Recovery varies by individual, and patients are advised not to drive until they have received clearance. Professional drivers should discuss vocational licence requirements with their cataract surgeon before the procedure.
How long does cataract surgery take to recover from?
Cataract surgery itself takes approximately 15 to 30 minutes per eye and is performed as a day procedure. Most patients notice improved vision within 24 to 48 hours. Full recovery, including resuming physically demanding work, typically takes one to four weeks. Your cataract specialist in Singapore will provide a recovery plan based on your occupation and individual healing.
Can cataracts affect your ability to keep a driving licence in Singapore?
Yes. Vocational and standard driving licences in Singapore require minimum visual acuity standards. Advanced cataracts can reduce vision below these thresholds, which may affect a driver’s ability to pass a vision assessment. Early eye cataract surgery, before the condition progresses significantly, typically allows patients to meet licensing requirements again following recovery.There is a common misconception that cataracts must be “ripe” before treatment, that patients should wait until the condition is severe before considering surgery.
