Title: Is the Routine Pressure Dressing After Thyroidectomy Necessary? A Prospective Randomized Controlled Study
Brief Summary: Thyroidectomy is an operation that is commonly performed. After an operation a pressure dressing by Hypafix is usually used due to the belief that it will help to reduce complications such as post-operative bleeding or haematoma. However, the practice is uncomfortable to patients and makes it hard to detect early haematomas.

We carried out a prospective randomised study to study the role of pressure dressing after thyroid surgery by evaluating the amount of fluids collected in the operative bed by ultrasonography compared with normal dressing.


Options:
A: Inclusion Criteria:

* Subject has a cataract and is expected to undergo unilateral clear corneal cataract surgery with phacoemulsification and implantation of a posterior chamber monofocal intraocular lens through an incision ≤ 3.5mm in width measured after IOL implantation using internal calipers.

Exclusion Criteria:

* Any intraocular inflammation in the study eye that was present during the screening slit-lamp examination or presence of ocular pain in the operative eye as rated on the pre-operative NRPS
* Previous surgery (laser or incisional) or ocular trauma to the operative eye or planned multiple procedures during cataract/IOL implantation surgery
* Potential BCVA in fellow eye worse than 20/40 as assessed by the clinical Investigator
* Active or history of chronic or recurrent inflammatory eye disease (iritis, scleritis, uveitis, iridocyclitis, rubeosis iritis), evidence of acute external ocular infections, intraocular infection, dysthyroid ophthalmopathy, nasolacrimal duct obstruction, active chalazion, uncontrolled blepharitis, uncontrolled and clinically significant dry eye syndrome, anything more than trace guttata (\>10 guttae in the central 6 mm of cornea), evidence of glaucoma/glaucoma suspect, corneal dystrophy or other ocular disease that would interfere with study evaluations
* Subject is currently receiving antineoplastic therapy
* Use of topical ocular steroids within 14 days and/or systemic steroids (excluding inhalants) within 30 days prior to surgery.
* Subject is an insulin-dependent diabetic or has background diabetic retinopathy (BDR), proliferative diabetic retinopathy (PDR) or compromised macular function
