Understanding Cataracts: The Foundation of Change

A cataract is the clouding of the eye’s natural lens, typically associated with aging but also influenced by genetics, systemic diseases, trauma, and environmental factors. In the past, cataracts were treated only when vision loss became severe enough to interfere significantly with daily life.

Earlier approaches focused on necessity rather than optimization. Surgery was often delayed, outcomes were unpredictable, and recovery could be prolonged. However, growing awareness, better diagnostics, and improved surgical tools laid the groundwork for what would eventually become the cataract surgery renaissance.

A Look Back: Cataract Surgery Before the Renaissance

To truly appreciate the cataract surgery renaissance, one must understand where it began.

Early Surgical Techniques

• Large incisions

• Stitches required

• Longer hospital stays

• Extended visual recovery

• Higher complication risks

Patients were often advised to “wait until the cataract matures,” a concept that is now largely outdated. Visual rehabilitation could take weeks or even months, and refractive accuracy was limited.

Despite these challenges, these early methods paved the way for innovation, acting as stepping stones toward safer and more refined techniques.

Personalization: Cataract Surgery Through My Lenses

What truly defines the cataract surgery renaissance is personalization. No two eyes are the same, and modern cataract surgery respects that truth.

Patients today are asked:

• How do you use your vision daily?

• Do you read often?

• Do you work on screens?

• Do you drive frequently at night?

These answers shape surgical planning, lens choice, and expectations. Cataract surgery is no longer a one-size-fits-all solution—it is a tailored visual experience.

Patient Experience: Redefined and Refined

Another hallmark of the cataract surgery renaissance is the transformation of the patient journey.

Before Surgery

• Clear counseling

• Visual simulations

• Shared decision-making

• Reduced anxiety through education

During Surgery

• Comfortable environment

• Minimal discomfort

• Short procedure time

After Surgery

• Rapid recovery

• Early visual improvement

• Structured follow-up

• High satisfaction rates

The emotional and psychological aspects of care now receive as much attention as the surgical steps themselves.

---

Safety First: Lower Risks, Better Outcomes

Safety improvements are a cornerstone of the cataract surgery renaissance.

Modern cataract surgery boasts:

• Extremely low complication rates

• Enhanced infection control

• Better management of complex cases

• Improved outcomes even in high-risk patients

What was once considered risky is now routine, thanks to refined protocols and experience.

---

Expanding Indications: Earlier Surgery, Better Quality of Life

In the past, patients were advised to delay surgery. Today, the cataract surgery renaissance supports earlier intervention when quality of life is affected.

Benefits of earlier surgery include:

• Better visual function

• Easier surgical removal

• Faster recovery

• Improved daily performance

This proactive approach reflects a broader understanding of vision as a key component of overall well-being.

---

I have been lucky to be a part of  the evolution of cataract surgery along side my accreditation as an Ophthalmologist and during the last three decades of my ophthalmology practice. Starting with ICCE(Intra capsular Cataract Surgery)to  ECCE(Extra Capsular Cataract Extraction) with IOL (Intra Ocular Lens) implant along with use of the microscope for the entire procedure, during my post graduation and residency and then phacoemulsification with IOL implant, to begin with – rigid PMMA IOLs to foldable IOLs- hydrophilic, hydrophobic, square edge, Toric to multifocals and EDOFS-  I have witnessed it all. Today, with having used FLACS(Femto laser assisted cataract surgery)system, the so called “Laser cataract surgery” along with the  gold standard phacoemulsification , side by side for almost a decade, I place on record, the leaps  in cataract surgery-

implanting an intraocular lens after cataract removal was the first major revolution in cataract surgery. This was followed by the switch to phacoemusification with a sub 3mm incision and no stitches which raised the bar of cataract surgery  rapidly inspite of the steep learning curve for surgeons and a pocket pinch for the patient. With time as the phacoemulsification systems , the intraocular lenses  and surgeons skills improved , we reached the quintessence of cataract surgery which now can undoubtedly be called one of the most successful surgery in all of medicine. Today, cataract surgery has evolved into a refractive procedure, in which expectations of spectacle independence are commonplace.

With the turn of the first decade of the new century , we were very excited with the advent of FLACS ( Femto Laser Assisted Cataract Surgery)or “Laser Cataract Surgery” which made tall claims of performing the steps of Phacoemulsification with Laser. Delving into the depths of FLACS, we discovered that FLACS could do only the first three preliminary steps of cataract surgery: 1)making the incision (claimed bladeless)which has to be opened with blades, 2)Capsulorrhesis – making the opening for removing the cataract- we don’t need that as any Eye Surgeon proficient in phacoemulsification has to first master doing a Capsulorrhesis 3)Dividing the cataract into pieces – this too has to be done by the surgeon in the very next step after FLACS where the nucleus needs to be chopped and sucked with the phaco handpiece and the surgeons skill. So FLACS performs only the first 3 preparatory steps with a struggle – has no added benefits to the patient or surgeon over the gold standard phacoemulsification. The laser does not obviate the need for phacoemulsification. Hence ,“ Laser Cataract Surgery” fell  far short of our expectations and has really nothing to do with laser.

Setting the record straight-

the transition from ICCE to ECCE- beginning of  the “microsurgery “ era and the advent of an intraocular lens (IOL) to replace the cataractous lens –, leading to improved refractive results after surgery was a quantam leap in cataract surgery as surgeons operated with precision under the microscope and patients had spectacle free distant vision which rid them of their high plus power aphakic spectacles

ECCE to phacoemulsification which provides sub 3 mm incision, no stitches, no injections and implantation of a foldable IOl (Monofocal,EDOF Toric )was a lifestyle changing procedure giving excellent visual outcomes, less spectacle dependence and allowing patients to get back to normal life in a span of about a couple of days.

FLACS performs the first 3 preliminary steps with hiccoughs, all of these three steps,  a proficient surgeon can perform without a glitch and therefore has no added benefits to the patient or surgeon over the gold standard phacoemulsification! It therefore has a long way to go before we talk of the next leap in cataract surgery!
