Eye care is no longer limited to basic diagnosis and standard surgery. With advanced diagnostic tools, clinicians can now detect and monitor subtle changes in the eye with far greater clarity, strengthening decision-making beyond what symptoms alone reveal.

At the same time, the scale of care in India is expanding. Cataract services have been delivered in mission mode, with targets rising to 105 lakh cataract surgeries for 2024–25. (Digital Sansad)

In this environment, network providers such as Centre For Sight are positioned as contenders, particularly for high-volume procedures supported by comprehensive “under-one-roof” care models.

For patients, the shift is meaningful, decisions are more informed, outcomes are more predictable, and recovery is smoother, because the plan is built on precise eye measurements, not guesswork.

The Evolution of Cataract Eye Surgery

Cataract surgery’s modern chapter is largely a story of smaller cuts, better planning, and more predictable vision, making it a key part of advanced cataract treatment today. In older approaches like intracapsular and extracapsular cataract extraction, incisions were around 12.0 mm and 10.0 mm, respectively; over time, this reduced to ~6–7 mm in manual small-incision cataract surgery (MSICS), and to ~2.2–2.8 mm with modern phacoemulsification.

Technology also changed what “good outcomes” mean. A major leap came with femtosecond-laser-assisted cataract surgery, also known as robotic laser cataract surgery, first reported in a human eye in 2008, with FDA clearance following in 2010, bringing higher precision in steps like capsulotomy for selected cases.

Pre-op planning now depends on precise measurements of axial length and corneal power, with optical biometry outperforming ultrasound in accuracy in many settings. Clinically, patient-reported results are strong too. AAO notes that up to 90% of first-eye cataract patients report improved function and satisfaction.

The Evolution of Refractive Surgery

Refractive surgery took off when it stopped being “one laser for everyone” and became a screening-led, customised journey.

LASIK eye surgery set the early template; it was patented in 1989, entered clinical use in the early 1990s, and the technology base matured quickly after the FDA approved excimer lasers for refractive surgery in 1995.

By 1998, multiple excimer laser systems had FDA approvals that enabled modern laser vision correction pathways, and by 2001, the FDA had approved IntraLase for laser-assisted flap creation, helping standardise one of the most sensitive steps of LASIK. By the mid-2010s, modern evidence reviews were reporting 99.5% of eyes achieving better than 20/40 uncorrected vision after LASIK, which became a real-world benchmark for “success.(AAO)

The last decade is when refractive care became truly procedure-matched. The FDA approved topography-guided LASIK in 2013, bringing Contoura planning, which is built on corneal mapping that can capture ~22,000 data points on the eye surface.

Then came lenticule-based correction. SMILE was introduced in 2011, FDA-approved for myopia in 2016, and expanded for astigmatism in 2018, a big shift toward flapless options.

Now the “advanced” layer includes newer-generation approaches like SILK (performed with the ELITA femtosecond platform), with peer-reviewed clinical data emerging in 2023–2024, and refined no-touch surface options like SmartSurfACE from 2015 and TransPRK launched in 2009.

Centre For Sight frames refractive care as a ladder of choices, offering SILK and SmartSurf/SmartSurfACE alongside customised planning like CustomEyes with FORESIGHT, so the “right procedure” is chosen after work-up, not before it.

Technology as the Backbone of Modern Eye Hospitals

Modern eye care is increasingly built around closing the guesswork gap, because many problems don’t neatly fit into one box. Centre For Sight frames its approach around a measurement-first pathway, where diagnostics guide the plan before surgery, and that starts with the basics done right, not just advanced machines.

At the first level, the work-up includes visual acuity assessment, refraction testing (objective and subjective), and AR-NCT (auto-refraction with non-contact tonometry) to capture both power and eye pressure early.

This is then strengthened with slit-lamp examination, dilated fundus evaluation, and procedure-led essentials like keratometry and pachymetry when refractive surgery or cataract planning is being considered.

From there, the network layers in precision tools like corneal mapping platforms such as Oculus Pentacam, Sirius, ORBScan II (with aberrometer), and Tomey topography help refine refractive planning and cataract measurements.

While Carl Zeiss OCT and digital fundus imaging support retinal rule-outs, Humphrey visual field testing with tonometry strengthens glaucoma risk assessment, so macular and optic nerve status are evaluated alongside cataract planning, not after it.

In the OT, the same plan-then-perform logic continues. The network uses femtosecond platforms such as Catalys and LenSx for suitable FLACS cases, alongside CENTURION and Stellaris systems for controlled phaco/MICS delivery.

For refractive care, it highlights CustomEyes, a surgery built on detailed corneal mapping, and links this to the launch of Asia’s first SCHWIND AMARIS 1050RS with AI-powered FORESIGHT, alongside early adoption of newer options like SMILE, SILK and surface procedures such as PRK, TransPRK, and SmartSurfACE.

The technology is treated as decision support, not a replacement for clinical judgement, which is where sub-specialist expertise becomes the next differentiator.

Why Skilled Specialists Still Matter Most?

Even with the best machines, outcomes still depend on the specialist who screens the case, reads the scans, and chooses the safest plan for that specific eye.

At Centre For Sight, that specialist depth is shaped by senior clinical leadership, including Prof. Dr. Mahipal S. Sachdev (Padma Shri), Chairman & Medical Director, with 42+ years of experience in ophthalmology. He is closely associated with advanced vision correction and anterior segment care, along with multiple refractive milestones, including SMILE in India.

The network also highlights Maj Gen (Dr.) JKS Parihar (Retd.), with 35+ years of experience, specialises in cataract surgery, glaucoma surgery, cornea transplant, keratoconus care, and ocular surface & dry eye treatment, the kind of overlap that matters when early symptoms don’t point to a single clear cause.

For cornea-led and refractive differentials, Dr. Rupal Shah brings 34+ years of experience across SMILE/LASIK, cataract care, glaucoma, keratoconus, and dry eye, while Dr. Tulika Chauhan adds 19+ years with a strong focus on cornea, cataract, keratoconus, cornea transplant, with fellowships at Massachusetts Eye and Ear, University of Harvard, and UCLA, show how sub-specialisation strengthens “right-procedure-for-right-eye” decision-making.

Future of Eye Care: What Lies Ahead?

Eye care is starting to move “upstream,” with AI helping spot risk before patients reach an operating table. In diabetic retinopathy (DR), autonomous and AI-led screening is already being used to close gaps, while India has launched an AI-driven community screening programme anchored by MadhuNetrAI to support earlier detection at scale.

Surgery is also entering a new era of precision. Robotic assistance is still early, but a first-in-human study reported 10 robotic-assisted cataract surgeries with no adverse events, pointing to where consistency and control head next.

Conclusion

Eye care’s next chapter looks less like “one procedure fits all” and more like earlier detection, tighter planning, and more customised correction.

Centre For Sight notes that the strongest outcomes will still come from pairing these tools with specialists, so precision stays patient-specific rather than just fancy technology-led.
