Senile Cataract Medication

No drug is available that has been proven to prevent the progression of senile cataracts. Medical therapy is used preoperatively and postoperatively to ensure a successful operation and subsequent visual rehabilitation.
Autonomic drugs used to ensure maximal pupillary dilation preoperatively, which is essential for a successful lens extraction. Short-acting mydriatics often are used. Most commonly used mydriatics are phenylephrine hydrochloride and tropicamide.
Direct-acting adrenergic agent available in 2.5% and 10% concentrations. Acts locally as potent vasoconstrictor and mydriatic by constricting ophthalmic blood vessels and radial muscles of the iris. Favorably used by many ophthalmologists because of rapid onset and moderately prolonged action, as well as the fact that it does not produce compensatory vasodilation. Most ophthalmologists prefer 2.5% to 10% concentration because of fewer risks of severe adverse systemic effects. Onset of action is within 30-60 min lasting for 3-5 h.
Tropicamide blocks the response of the sphincter muscle of the iris and the muscle of the ciliary body to cholinergic stimulation.
Nonsteroidal anti-inflammatory ophthalmics
Used for pain and inflammation associated with cataract surgery.
Nonsteroidal anti-inflammatory prodrug for ophthalmic use. Following administration, converted by ocular tissue hydrolases to amfenac, an NSAID. Inhibits prostaglandin H synthase (cyclooxygenase), an enzyme required for prostaglandin production. Indicated for treatment of pain and inflammation associated with cataract surgery.
Nonsteroidal anti-inflammatory prodrug for ophthalmic use. Following topical administration, this NSAID achieves high therapeutic intraocular levels. Inhibits prostaglandin H synthase (cyclooxygenase), an enzyme required for prostaglandin production. Indicated for treatment of pain and inflammation associated with cataract surgery.
Combination allows for maintenance of intraoperative mydriasis and reduces postoperative pain.
Ketorolac/phenylephrine ophthalmic is a proprietary FDA-approved combination agent that is added to the standard irrigating solution used during cataract surgery and other intraocular lens replacement procedures, including refractive lens exchange. Phenylephrine is an alpha1-agonist that prevents intraoperative miosis and ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that facilitates mydriasis and reduces postoperative pain.
Help decrease and control the inflammatory response following cataract surgery especially in the immediate postoperative period. The most commonly used ophthalmic steroid is prednisolone acetate 1%. Dexamethasone 0.1% ophthalmic solution sometimes is used as a generic alternative.
Topical anti-inflammatory agent for ophthalmic use. A good glucocorticoid that, on the basis of weight, has 3-5 times anti-inflammatory potency of hydrocortisone. Glucocorticoids act at the nuclear level by down-regulating transcription of inflammatory mediators. Thus, they reduce prostaglandin synthesis, block arachidonic acid activity, and inhibit edema, fibrin deposition, capillary dilation, and phagocytic migration of acute inflammatory response, as well as capillary proliferation, deposition of collagen, and scar formation. Indicated for treatment of steroid-responsive inflammation of palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe.
Decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reducing capillary permeability.
A potent corticosteroid approved for a wide variety of anterior segment surgical procedures, including cataract surgery, as well as acute noninfectious anterior uveitis. Provides powerful control of postoperative pain and inflammation in the cornea, anterior chamber, and, possibly, the retina.
An ester rather than a ketone steroid, provides FDA-approved control of pain and inflammation following cataract surgery, as well as anterior uveitis, contact lens–induced giant papillary conjunctivitis, and perennial and seasonal allergic conjunctivitis. Newer ointment and gel drop formulations are approved for cataract surgery pain and inflammation.
Broad-spectrum antibiotic ophthalmic solutions often are used prophylactically off-label in the immediate postoperative period. A number of topical antibiotics are used depending on the surgeon's preference, but, generally, medications are active against both gram-positive and gram-negative organisms.
Active against a broad spectrum of gram-positive and gram-negative organisms. Bactericidal action results from interference with enzyme DNA gyrase needed for bacterial DNA synthesis. In vitro and clinical studies have shown it to be active against following organisms: gram-positive (ie, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus viridans) and gram-negative (ie, Haemophilus influenzae, Pseudomonas aeruginosa, Serratia marcescens). Other organisms have been found to be susceptible in vitro but have yet to be firmly established by clinical studies.
A self-preserved topical fluoroquinolone approved for conjunctivitis. Prescribed frequently for cataract and other intraocular surgical procedures as infection prophylaxis. By virtue of its broad spectrum and preservative-free status, many surgeons also inject 0.1 mL directly into the anterior chamber at the conclusion of cataract surgery to prevent endophthalmitis.
A uniquely formulated fluoro-chloro fluoroquinolone that is bihalogenated for increased spectrum and potency. Highly effective against multiply drug-resistant strains of Staphylococcus aureus and Staphylococcus epidermidis. Not available for animal, farm, or systemic human use, presumably reducing resistance profiles. Excellent pharmacokinetics due to highly viscous Insite® vehicle.
An increased spectrum L-isomer of ofloxacin provides antibiotic coverage for all types of intraocular surgery.
A potent fluoroquinolone approved for bacterial conjunctivitis, like all the other listed fluoroquinolones herein, but used frequently for surgical prophylaxis.
Indicated for infections caused by susceptible strains of microorganisms and for prevention of corneal and conjunctival infections.
A commonly prescribed topical combination agent used for conjunctivitis and surgical prophylaxis. Available as a generic.
A commonly prescribed topical combination agent used for conjunctivitis and surgical prophylaxis. Much less likely to produce IOP elevations than dexamethasone-based combination agents.
