About the Practice

Long Island Ophthalmic Concepts (LIOC) is a premier ophthalmology practice of board-certified ophthalmologists and surgeons. Their highly trained team works out of offices in Bellmore and Great Neck, New York.

Long Island Ophthalmic Concepts is one of the last family-owned practices on Long Island. It’s a private practice group that operates in a densely populated community, where it’s often difficult to have close doctor-patient relationships.

Providers treat all patients like family, keeping in constant touch with them. The LIOC team offers exceptional, high-quality, comprehensive eye care to patients 12 and older. Their offices provide warm, welcoming environments.

Patients suffering from vision problems, cataracts, glaucoma, macular degeneration, pink eye, diabetic eye problems, and more can turn to the experts at LIOC for premium care. They take a holistic approach to medicine, offering state-of-the-art equipment and a top-notch, highly trained staff.

Patients are the number one priority for providers who maintain exceptional customer service. The LIOC team is one of Long Island’s best, with many years of experience and top-rated reviews.

They offer vision evaluations, eyeglass and contact lens prescriptions, dry eye treatment, and pediatric eye care services. They also offer cataract and LASIK surgery, glaucoma and macular degeneration treatments, diabetic eye care, pink eye treatment, and nutritional supplements.

The staff treats many Medicare patients and works with many insurance providers. They offer convenient hours, with appointments available on Saturdays.
