Retinal Detachment
In high myopes the sclera is larger than the retina causing the
retina to stretch and thin out in certain areas. There are more chances
of retinal holes, tears and detachment. A thorough retinal exam before
surgery is essential.
It is also predisposed by posterior capsule tear, vitreous traction,
vitreous inflammation, excessive exercise or lifting heavy weights.
Early detection can resolve such cases by pneumoretixopexy or
injection of gases, scleral buckle, vitrectomy with or without silicone
oil and retinal laser.

Endophthalmitis:
An infection of the eye manifesting three to ten days after surgery
(versus immediate onset of inflammation). It is very rare but the most
dreaded complication for a surgeon and patient alike. All focus should
be on prevention: including preoperative and postoperative antibiotic
drops, betadine (povidone-iodine) scrub of the eye prior to procedure,
attention to detail in draping, and sterile conditions during surgery.
People with low immunity, diabetes, wound leaks, complicated
surgery, and exposure to germs in hospitals have a higher chance of
contracting infections.
It manifests as pain, redness, and decreased vision.
The anterior chamber and vitreous cavity appear hazy with cells,
may even have fibrin. Treatment requires a vitreous sample for
cultures, injecting steroids and antibiotics in the vitreous. Vitreous
debulking or vitrectomy with further intra-vitreal drugs may rarely be
required.

Side Effects Related to Presbyopic Implants:

Glare
The eyes are supersensitive to light, as light is diffracted off the
multiple rings in multifocal or the optic zone in accommodative lens.
Antiglare or yellow tinted glasses help decrease this effect. Treatment
of dry eyes, astigmatism, residual refractory power and posterior
capsule cells and wrinkles help decrease glare. Neuroadaptation helps
overcome this problem.
