RETINA • VITRECTOMY • FLASHES & FLOATERS • URGENT REFERRALVitrectomy & Retinal Surgery in Nepal: Warning Signs, Referral & Recovery Questions
A vitrectomy is specialist eye surgery used for certain problems of the retina and vitreous. It is not treatment for ordinary blurry vision. New flashes, many floaters, a curtain-like shadow or sudden vision loss can need urgent retinal assessment.
WhatsApp for Initial Guidance Call +977 9841466716Emergency warning: sudden vision loss, a dark curtain, rapidly increasing floaters, flashes with a shadow, serious eye injury or severe pain needs urgent medical assessment. Do not wait for an online reply or routine optical appointment.
What is a vitrectomy?
The vitreous is the clear gel that fills the middle of the eye. In a vitrectomy, a retinal surgeon makes tiny openings in the eye and removes some or most of this gel to treat a problem affecting the retina or vitreous. Depending on the reason for surgery, the surgeon may also use laser treatment, remove scar tissue, or place air, gas or silicone oil inside the eye.
Vitrectomy is specialist surgery. Vision Concern provides eye assessment, visual testing, optical support and referral guidance; it does not claim to perform retinal surgery. A retinal surgeon determines diagnosis, urgency, procedure choice, recovery instructions and expected results.
Why might a retinal surgeon consider vitrectomy?
| Condition or problem | Why surgery may be discussed | Important point |
| Retinal detachment or retinal tear | To repair/reattach the retina in selected cases | Time matters; a curtain or sudden field loss is urgent. |
| Vitreous haemorrhage | To clear blood clouding the eye in selected cases | The cause must be diagnosed, including diabetes-related disease where relevant. |
| Macular hole or macular pucker | To treat selected central-retina problems | Symptoms may include distortion or reduced central detail. |
| Diabetic retinal disease with bleeding/scar tissue | To address selected advanced retinal complications | Blood-sugar and medical care remain important alongside eye treatment. |
Flashes, floaters and shadows: when should you act?
Floaters are common and may be harmless, especially if they are long-standing and unchanged. But a sudden increase in floaters, new flashing lights, a veil/curtain, a missing area of vision, or new blur can be a retinal warning sign. A dilated retinal examination is the way to tell whether there is a tear or detachment; symptoms alone cannot confirm the cause.
Read Vision Concern’s existing Retinal Detachment Guide and Eye Floaters guide. If your symptoms are new or worsening, seek urgent medical assessment rather than waiting for a blog answer.
What happens around surgery?
The surgical plan is individual. A retinal surgeon may use local or general anaesthesia depending on the case and will explain the operation, risks, alternatives and follow-up plan. If a gas bubble is placed in the eye, the surgeon may give strict positioning and travel instructions. Never fly or travel to higher altitude after intraocular gas unless the treating retinal surgeon has specifically cleared it.
| Question to ask the retinal surgeon | Why it matters |
| What exactly is the diagnosis and urgency? | Different retinal problems need different timing and treatment. |
| Will you use gas, oil, laser or another technique? | This may change positioning, travel and follow-up requirements. |
| What recovery restrictions apply to me? | Follow the surgeon’s individual advice, not a generic internet timetable. |
| Who should I contact after surgery if symptoms worsen? | You should leave with a clear urgent-contact plan. |
Vision Concern assessment and referral support
For non-emergency concerns, a Comprehensive Eye Examination can assess vision, prescription and relevant eye-health concerns. If findings or symptoms require specialist retinal care, an appropriate referral may be recommended. The examination does not replace urgent hospital assessment when danger signs are present.
Vision Concern’s trust commitments apply across routine care: ISO 9001 certified eye clinic, member of the International Opticians Association (UK), professional optical assessment, Best Patient Service Award—Ireland 2018, and three Kathmandu branches in Lazimpat, Boudha–Tushal and Makalbari. Ask via WhatsApp which branch is most practical for a non-emergency appointment.
For tourists, expats and families travelling in Nepal
Visitors should not postpone sudden retinal warning signs until they return home. If you have a stable prescription problem or need replacement glasses while travelling, Vision Concern can help through its Eye Care for Tourists & Expats service. If you have new flashes, a curtain or sudden loss of sight, seek urgent medical care first.
Need help deciding the next step?
For routine assessment, send your symptoms, which eye is affected and when they started. For sudden sight loss or a retinal emergency, arrange urgent medical assessment immediately.

No. Floaters have many causes, and surgery is only considered in selected situations by a retinal surgeon. New or changing floaters still need timely assessment.
It may be painless. A dark curtain, sudden flashes, floaters or loss of side vision are warning signs that need urgent evaluation.
In some advanced diabetic-retinal situations with significant bleeding or scar tissue, a retinal surgeon may consider it. Regular diabetic eye reviews are important.
Do not fly if an intraocular gas bubble is present unless your treating surgeon has specifically cleared it. Follow the surgeon’s written instructions.
No. Vision Concern provides eye assessment and referral guidance; vitrectomy is performed by a qualified retinal surgeon in an appropriate surgical setting.
