Dr. Sagnik Surya Das – Ophthalmologist and Cataract & Cornea Surgeon in Kolkata

Dr. Sagnik Surya Das is a Consultant Ophthalmologist associated with Fortis Hospital & Kidney Institute, Gariahat, Kolkata. With 8 years of professional experience listed by Fortis Healthcare, he specialises in the evaluation and surgical management of cataracts, corneal disorders and conditions affecting the clarity and health of the cornea.

Dr. Sagnik Surya Das completed his MBBS from Kasturba Medical College, Manipal, Karnataka, followed by an MS in Ophthalmology in Chennai. He subsequently completed advanced fellowship training in Cornea, Cataract and Refractive Surgery at Susrut Eye Foundation & Research Centre, Kolkata, where he also worked as a Consultant.

His principal areas of clinical expertise include complex cataract surgery, phacoemulsification and corneal transplantation. According to his official hospital profile, he has performed more than 5,000 phacoemulsification procedures and has extensive surgical experience in managing corneal conditions requiring specialised intervention.

Dr. Das has documented experience in corneal transplantation techniques including Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK), optical penetrating keratoplasty and therapeutic penetrating keratoplasty. These procedures address selected diseases involving corneal transparency, structural integrity and visual function. The appropriate surgical method depends on the patient's corneal condition and clinical assessment.

He also has expertise in corneal collagen cross-linking (CXL), a treatment used to strengthen the cornea and reduce progression in selected patients with keratoconus. His background in cataract and corneal surgery supports the assessment of patients who require specialised ophthalmic evaluation and individualised surgical planning.

Patients seeking consultation for cataracts, keratoconus, corneal disease or corneal transplantation in Kolkata can refer to Dr. Sagnik Surya Das's official hospital profile for appointment information. A detailed ophthalmic examination is important for determining the diagnosis, treatment options, potential benefits and associated risks.

Cataract Surgery

Cataract surgery is performed to remove the eye's cloudy natural lens and replace it with an artificial intraocular lens. It may be recommended when cataracts cause blurred vision, glare, difficulty reading or problems with daily activities. The choice of surgical technique and lens depends on a detailed eye examination.

Phacoemulsification Surgery

Phacoemulsification is a commonly performed cataract surgery technique that uses ultrasound energy to break up the cloudy lens before its removal through a small incision. An artificial intraocular lens is usually implanted afterward. This approach generally allows faster visual recovery than conventional large-incision cataract surgery, although recovery varies among patients.

Complex Cataract Surgery

Complex cataract surgery involves treating cataracts in eyes with additional anatomical or medical challenges. These may include dense cataracts, weakened lens-support structures, previous eye surgery or associated corneal abnormalities. Careful preoperative assessment, specialised surgical techniques and appropriate follow-up are essential for managing additional risks and supporting visual rehabilitation.

Corneal Transplant Surgery

Corneal transplantation, also called keratoplasty, replaces damaged or diseased corneal tissue with suitable donor tissue. It may be considered when corneal scarring, swelling or structural damage significantly affects vision or eye health. Different transplantation techniques are available depending on which layers of the cornea require replacement.

DSAEK Corneal Transplantation

Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) is a partial-thickness corneal transplantation procedure used for conditions affecting the inner endothelial layer of the cornea. It replaces dysfunctional tissue with donor tissue while preserving much of the patient's original cornea. It is commonly considered for selected cases of endothelial failure and corneal swelling.

Optical Penetrating Keratoplasty

Optical penetrating keratoplasty is a full-thickness corneal transplant performed primarily to improve vision when extensive corneal disease or scarring affects transparency. The damaged cornea is replaced with a donor corneal button. Following surgery, patients require monitoring for graft rejection, infection, astigmatism and other possible complications.

Therapeutic Penetrating Keratoplasty

Therapeutic penetrating keratoplasty may be performed when severe corneal infection, progressive tissue destruction or perforation threatens the eye's structural integrity. Unlike transplantation primarily intended to improve vision, this procedure focuses on removing diseased tissue and preserving the eye. Visual improvement depends on the underlying disease and postoperative recovery.

Keratoconus Management

Keratoconus is a progressive condition in which the cornea becomes thinner and develops an irregular cone-like shape. It can cause blurred vision, irregular astigmatism and increased sensitivity to light. Management depends on disease severity and progression and may include corrective lenses, specialised contact lenses, cross-linking or corneal transplantation.

Corneal Collagen Cross-Linking (CXL)

Corneal collagen cross-linking is a procedure designed to strengthen corneal tissue and limit progression in selected patients with keratoconus or other corneal ectatic disorders. It typically uses riboflavin eye drops and controlled ultraviolet-A light. Its primary purpose is to stabilise the cornea rather than guarantee improved or glasses-free vision.

Corneal Disease Evaluation and Management

Corneal diseases can affect the transparent front surface of the eye and cause blurred vision, discomfort, light sensitivity or reduced clarity. Assessment may involve slit-lamp examination, corneal imaging and other investigations. Treatment depends on the cause and can range from medication and monitoring to specialised corneal procedures or transplantation.

Corneal Surgical Consultation

A corneal surgical consultation helps determine whether a patient with corneal damage, scarring or progressive disease may benefit from surgery. The evaluation considers the underlying diagnosis, corneal thickness, visual function and overall eye health. Depending on the findings, treatment options may include cross-linking, partial-thickness transplantation or full-thickness keratoplasty.
