Outpatient Department (OPD) services in Ophthalmology cover comprehensive outpatient eye care, ranging from routine vision screening and refraction to specialized diagnostic tests and minor clinical procedures.

When a patient arrives at the Ophthalmology OPD, they undergo foundational workup tests administered by an optometrist or ophthalmic assistant prior to specialist consultation:

• Visual Acuity Assessment: Measuring clarity using Snellen, LogMAR, or digital vision charts.
• Refraction & Prescription: Autorefraction and subjective trial lenses to prescribe corrective glasses or contact lenses.
• Intraocular Pressure (IOP) Measurement (Tonometry): Screening for glaucoma using Non-Contact Tonometry (puff test) or Goldmann Applanation Tonometry.
• Slit-Lamp Biomicroscopy: Magnified examination of the anterior segment (cornea, iris, lens, and conjunctiva).
• Fundus / Dilated Eye Exam: Evaluating the retina, optic nerve, and macula using an ophthalmoscope or specialized lenses following application of dilating eye drops.

High-resolution imaging and functional evaluations performed in the outpatient clinical setup:

Minor therapeutic treatments performed directly in the OPD procedure room without requiring hospital admission:

• YAG Capsulotomy: Treats posterior capsule opacification ("after-cataract").
• YAG Peripheral Iridotomy (PI): Creates a tiny pathway for fluid flow in narrow-angle glaucoma.
• Retinal Photocoagulation / Retinal Laser: Treats diabetic retinopathy, retinal tears, or vascular occlusions.

• Chalazion incision and curettage, foreign body removal, lacrimal sac probing/syringing for blocked tear ducts, and suturing superficial eyelid lacerations.

• Schirmer's testing, tear film break-up time (TBUT) analysis, punctal plug insertion, and low-vision rehabilitation counseling.
