Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Preoperative assessment includes proper history taking and ocular examinations.Ocular examination includes baseline visual acuity, slit lamp examinations to ascertain the cataract grading, anterior chamber reactions preoperatively, intraocular pressure measurement via applanation tonometry and fundus examinations using 78D condensing lens. Cornea endothelial examinations will be done by using non-contact TOPCON Specular Microscopy model SP-1P.
On the day of surgery, patients will be informed about the two different antibiotics available that will be used at the end of cataract surgery. A written informed consent will be obtained from the patient.
Patients will be randomized before entering the operating theatre. Sealed envelopes total of 4 will be prepared by the researcher; 2 of which will be labelled as A and another 2 envelopes will be labelled as B. The researcher will randomly pick 1 envelope and allocate to patient's file. The staff nurse in charge will then open the envelope, label A or B will then be pasted on the patient's file (rear part) for documentation.
Cataract surgery will be performed byusing Centurion®Vision System, Alcon, Texas, United Stated of America (USA) phacoemulsification machine. 0.3 ml of levofloxacin 0.5% ophthalmic solution (Cravit®, Santen) will be syringed out and at the conclusion of cataract surgery, the solution of 0.1ml which has 0.5 mg levofloxacin will be injected via intracameral into the anterior chamber through the side port wound using a tuberculin syringe in a 27 gauge cannula.
On the other hand, at the beginning part of surgery, cefuroxime will be diluted by the researcher. In order to reduce dilution error and contamination, dilution will be done strictly according to a standardised protocol that was obtained from Malaysian Clinical Practice Guideline. The vial contains 750 mg of cefuroxime powder is diluted with 7.5 ml of Balanced Salt Solution (BSS). 1 ml of the solution will be withdrawn and added with 9 ml of BSS. Then, 0.1 ml of solution which is equivalent to 1 mg of cefuroxime will be aspirated and kept a side. Then the antibiotic of 0.1 ml will be given as intracameral to patient using a tuberculin syringe in a 27 gauge cannula at side port wound at the end of surgery. The side port wound will then be sealed by stromal hydration and checked for water tightness.
This will be followed by instillation of topical guttae ciprofloxacin 0.3% (Ciloxan, Alcon) and guttae dexamethasone 0.1% (Maxidex, Alcon) and eye shield will be applied before leaving the operating theatre.
Patient will be reviewed again after 2 hours post operatively at the slit lamp and eye drops guttae ciprofloxacin 0.3% and guttae dexamethasone 0.1% will be instilled every 2 hours (5 minutes apart from one eye drop to another) for the first one week post-surgery. Upon discharge, patient will be reviewed again in eye clinic after 1 week and during this visit, these eye drops will then be tapered to 4 hourly for two weeks then six hourly for two weeks until next review. After one month the eye drops will be discontinued.
Patients will then be reviewed after one week, one month and three months post operation. During each visit, patient will be examined under slit lamp to look for anterior chamber reaction and to measure intraocular pressure. They will undergo specular microscopy examination to assess cornea endothelial cell count and morphology and central cornea thickness.

Then, 0.1 ml of solution which is equivalent to 1 mg of cefuroxime will be aspirated and kept a side. The dissolution of the antibiotic is confirmed by naked eye. Then the antibiotic of 0.1 ml will be given as intracameral to patient using a tuberculin syringe in a 27 gauge cannula at side port wound at the end of surgery.
