Lahan Eye Care Centre is fully equipped with the most modern technology for performing sutureless cataract surgeries. The Department of Cataract has made tremendous progress in the last years. Four new dedicated state of the art operation theatres have vastly increased our capacity and the patient turnover time has been significantly reduced. We also have increased the capacity in our out-patient department with streamlined systems for consultation & investigation.
Cataract is the leading cause of decreased vision and blindness in our country. It can be cured by a simple cataract extraction microsurgery, which, these days is performed using advanced technology in a short time.
We are one of the few institutions in the world to have the 3 top platforms for cataract surgery – the Infinity, the Signature and the Stellaris. All these machines can be used for the latest Micro-Coaxial Cataract Surgery (MICS), or removal of the cataract through a 2mm (or less) incision with the implantation of foldable intraocular lenses (IOLs). We offer our patients the latest in IOL technology including the accommodative Crystalens HD, the ReSTOR & Tecnis multifocal IOLs and the astigmatism correcting Toric IOLs. We offer the latest generation of multifocal IOLs with astigmatism correction and the Implantable Collamer Lens as an option in correcting refractive errors. To minimize calculation errors in the implanted IOLs we now have the Immersion Biometry and the non-contact Lenstar which works by the laser interferometry principle. We perform upwards of 10,000 surgeries annually, with a large number of them being MICS with high end IOLs.

Ageing is the most common cause of cataract. Every person gets it sooner or later, especially people over 60yrs of age. Other causes include diabetes, injury, usage of certain medications, and secondary to other eye diseases such as uveitis and glaucoma. Cataracts can occur early in diabetes, myopia (short sight) and as a hereditary predisposition.

IOL power calculation Biometry (IOL power calculation) is done by trained personnel and every endeavour is made to ensure accurate results. It requires measurement of the axial length (length of the eyeball) and corneal keratometry (power of the cornea). Axial length measurements are done using both laser and ultrasound technologies using different machines. This is done to avoid errors as much as possible. Corneal keratometry measurements prior to cataract surgery is calculated using a host of equipment including
This also allows us to manage complex cases such as patients coming for cataract surgery after having undergone keratorefractive surgery (LASIK, PRK etc) or those with Keratoconus.
Biomechanical imaging of the cornea prior to cataract surgery is possible using: Corvis & Ocular Response Analyzer.
Is there much discomfort after surgery? Cataract surgery is pretty much painless and so is the post-operative period. There is mild irritation (or foreign body) sensation for a few days. There may be mild redness & watering of the eyes which again subside in a few days.
What do I do after surgery? There is no need for bed rest after surgery. One can walk, eat normally, watch TV and be normal around home on the day of the surgery. One needs some protective glasses only when outdoors.
What about the post-operative treatment?
When can I resume my normal work?
What about post-operative restrictions?
When will I see well?
Will I need glasses after surgery?
How do I clean my eye after surgery?
Can I travel after surgery?
Our operation theatre has a stainless Steel modular design with laminar air flow and HEPA filters. We have state of the art equipment for performing cataract surgery some of which are:
We are fully equipped to take up complex paediatric surgeries under general anaesthesia. All this is constantly monitored by team of anaesthetists, nurses and supporting staff.
The femtosecond laser is the latest breakthrough in advanced cataract surgery as a means to providing precision and safety to crucial steps of the surgery. These include creation of surgical incisions, circular opening on the lens surface (capsulotomy), and fragmentation of the human lens. The additional advantage of this laser is that it is accurate enough to plan incisions in the peripheral cornea to aid in the correction of pre-existing corneal astigmatism (cylindrical power).
In standard phacoemulsification, the corneal incisions are made with a metal blade. The circular opening in the lens capsule from which to remove the cataract and place an artificial lens is made using a sharp bent needle. The surgeon then divides the lens manually to aid its removal after emulsification with ultrasound energy.
In bladeless cataract surgery, the Femtosecond laser replaces all three steps. The entire process is automated using the machine’s integrated OCT guided imaging system. Since the surgery is done with laser, the incisions are more precise and the capsular opening is perfectly centred and round. This allows for exact placement of the artificial lens implant optimizing visual outcomes. This is of utmost importance in premium intraocular lenses such as aspheric design IOLs, Toric IOLs and Multifocal IOLs where the slightest error can compromise the quality of vision. Moreover, as the laser divides the lens into small fragments, the amount of ultrasound energy used to remove the cataract is greatly reduced, which in turn helps in early visual recovery.
Phakic posterior intraocular lens implantation is currently an excellent option for high myopes who desire spectacle independence but are not good candidates for LASIK or photorefractive keratectomy (PRK). Facilities available for planning ICLs include
