Does retinal detachment need to be operated on urgently?

Retinal detachment is an eye emergency, and the timing of surgery can have a major impact on vision after treatment. Prompt surgery is particularly important before the macula, the part of the retina responsible for central vision, becomes detached. Even if the macula has already detached, delaying treatment may allow further damage to the light-sensitive cells. If you are diagnosed with retinal detachment, seek assessment by a retinal specialist on the same day rather than waiting several days. The surgeon will determine the most appropriate timing based on macular involvement and how far the detachment has progressed.

Will I have to lie face down after retinal detachment surgery?

Not always. Your postoperative positioning depends on the location of the retinal breaks, whether air, gas, or silicone oil was used, and the surgical technique. Some patients need to keep their head ...

Can retinal detachment happen again after surgery?

Yes. Retinal detachment can recur because of a new retinal break, remaining traction, or proliferative vitreoretinopathy, among other causes. Keep your scheduled retinal follow-up appointments, and se...

How long should I stop wearing contact lenses before my preoperative examination?

For accurate measurements, we generally recommend stopping contact lens wear for at least one week before the examination. Contact lenses can temporarily alter corneal shape and tear-film quality, aff...

I had LASIK or LASEK years ago, but my vision has become blurry again. Can I have another procedure?

A second procedure may be possible, but the first step is to identify why your vision has changed. Treatment will differ depending on whether the cause is residual nearsightedness or astigmatism, dry ...

Is enhancement surgery possible after SMILE?

Some patients may be candidates for further vision correction after SMILE. We first assess the depth of the original treatment, remaining corneal tissue, corneal shape, current refractive error, and t...

Why is corneal thickness particularly important for a second laser procedure?

An enhancement procedure removes additional tissue from a cornea that has already undergone surgery. We consider the residual stromal bed, total corneal thickness, corneal shape, and expected treatmen...

What is the difference between monofocal and multifocal intraocular lenses?

A monofocal intraocular lens is generally designed to focus at one distance. Multifocal lenses are designed to reduce reliance on glasses at multiple distances. However, some multifocal IOLs can cause...

When does an intraocular lens need to be exchanged?

IOL exchange may be considered if a lens becomes dislocated, if its power is significantly different from what the eye needs, or if substantial lens-related symptoms persist despite treatment of other...

My intraocular lens has moved out of position. How can it be treated?

When an IOL moves out of its normal position, vision may become blurry or objects may appear doubled. Treatment may involve repositioning or exchanging the lens. If there is insufficient tissue to sup...

What is scleral fixation of an intraocular lens?

Scleral fixation is a procedure used when an IOL cannot be supported reliably in its normal position. The lens haptics are secured to the sclera, the white outer wall of the eye. The Yamane technique ...

Can an intraocular lens still be exchanged many years after cataract surgery?

An older IOL may still be exchanged, but surgery can become more challenging as adhesions develop between the lens and capsular bag over time. We compare the likely benefits and risks of exchange and ...

If I have a retinal problem, does that mean I need surgery?

Not always. Conditions such as epiretinal membrane, macular hole, retinal detachment, and vitreous hemorrhage require different approaches depending on their type and severity. Some can be monitored o...
