Diclofenac sodium is a potent nonsteroidal anti-inflammatory drug with analgesic activity. When instilled as a topical 0.1% solution in a limited number of patients undergoing cataract surgery, diclofenac limits surgically induced miosis, reduces signs of ocular inflammation, does not cause elevations in intraocular pressure, and reduces the occurrence and severity of cystoid macular oedema. Preliminary findings suggest a niche for topical diclofenac in other ocular inflammatory conditions such as iritis, episcleritis and conjunctivitis, although its efficacy in these areas awaits confirmation. The drug appears well tolerated, apart from a transient burning sensation after instillation in some patients. Ocular diclofenac thus appears well suited as a local anti-inflammatory adjunct to cataract surgery, and may be useful in some other inflammatory ocular conditions.

Diclofenac sodium 0.1% (Voltaren) prevents surgically induced miosis during extracapsular cataract extraction in a more long lasting way than indomethacin 1% (Indocid). Just before the IOL-implantation, in eyes treated with diclofenac sodium eye drops, the apparent mean pupil size was constricted by approximately 1 mm less than in the control group (p.01). At the same critical moment, 50% of the pupils treated with diclofenac sodium and only 20% of the pupils in the control and indomethacin groups were larger than 6 mm.

To test antiradical medicines effect the chemical production of singlet oxygen (NaClO + H2O2) was investigated. The quantity singlet oxygen chemiluminescence was decreased in the presence of Japanese Catalin and Chine Baineiting, antirheumatic Voltaren and less strong Finish Catachrome and Carnosine. American Quinax does not possess such an effect. One of the possible starting mechanisms causing different diseases (atherosclerosis, cataract etc.) is destruction of biomembranes by active forms of oxygen.

Two prospective, randomized, double-masked studies were conducted evaluating the analgesic effect of topical eyedrops after radial keratotomy (RK). One study of 117 consecutive initial RK procedures compared topical ketorolac (Acular) with topical diclofenac (Voltaren), and another study of 23 consecutive initial RK procedures compared topical ketorolac with a control medication (HypoTears). Topical ketorolac was significantly more effective than the control but not significantly different from topical diclofenac. The onset of analgesic effect of these topical nonsteroidal anti-inflammatory drugs is longer than one hour. The analgesic effect of oral acetaminophen #3 significantly augments that of topical diclofenac drops for those experiencing any discomfort by six hours after surgery.

The eyes of 65 consecutive radial keratotomy patients were treated topically with either diclofenac sodium 0.1% (Voltaren) solution or with Tears Naturale (control group) preoperatively and postoperatively in a prospective, randomized, double-masked study. During the first postoperative day, patients completed a questionnaire on discomfort level present at 15 minutes and at one, three, six, and 18 hours after surgery. Patients treated with topical diclofenac were generally more comfortable than patients in the control group. They had a significantly lower rate of "moderate" or "severe" discomfort and a higher rate of less than "mild" discomfort. Peak discomfort occurred at three hours in both groups. The prescribed optional oral analgesic was taken by 48.5% of patients in the diclofenac group and by 71.9% of those in the control group.

A 66-year-old woman developed severe and recurrent scleritis and uveitis after neodymium:YAG capsulotomy performed 18 months after cataract extraction. Four cracks on the intraocular lens and plastic splinters in the vitreous indicated that excessive laser energy had been used. Inflammation was treated successfully only when a combination of dexamethasone acetate 0.1% drops (Maxidex), drops of diclofenac sodium 0.1% (Voltaren Ophtha), and systemic diclofenac sodium (Voltaren) was used. Inflammation might be explained by chronic irritation of the ciliary body by a displaced haptic or by an immune reaction triggered by damage to the ciliary body at the time of excessive posterior capsulotomy.

We compared the postoperative anti-inflammatory effect of diclofenac sodium 0.1% and dexamethasone phosphate 0.1% in a prospective, randomized, double-masked pilot study. Anterior chamber inflammation was evaluated by measuring aqueous flare and cells with a laser flare-cell meter at one, three, 12, 30, and 60 days after cataract surgery. Flare values in the two groups did not significantly differ at any time, nor did aqueous cell counts at one, three, 12, and 60 days after surgery. At 30 days, however, cell count was significantly lower in the diclofenac group. Diclofenac sodium seems to be as potent as dexamethasone phosphate, as good as anti-inflammatory agent, and may replace corticosteroid therapy after cataract surgery.

Nonsteroidal antiinflammatory drugs have unique properties that aid the cataract surgeon. In phacoemulsification surgery, patients routinely receive nonsteroidal antiinflammatory drugs along with their dilating drops to inhibit intraoperative miosis. After surgery, these drugs can control inflammation and inhibit the development of cystoid macular edema. We present two prospective randomized studies. In the first, diclofenac sodium was compared with prednisolone acetate for control of postoperative inflammation. In the second, diclofenac sodium was compared with flurbiprofen for inhibition of intraoperative miosis. Diclofenac sodium was found to be as effective as prednisolone acetate for control of postoperative inflammation and as effective as flurbiprofen for inhibition of intraoperative miosis. Thus, whereas in the past we used a nonsteroidal antiinflammatory drug before surgery for inhibition of intraoperative miosis and a steroid drop in the postoperative period to control postsurgical inflammation, we now have equal efficacy using the same drug in the entire perioperative period.

In a prospective, randomised, double-masked, parallel-group study we compared the antiinflammatory effect of diclofenac sodium 0.1%, flurbiprofen 0.03%, and indomethacin 1.0% ophthalmic suspension in 99 patients undergoing phacoemulsification and posterior chamber lens implantation. The reduction in anterior chamber flare from day 1, as measured with the laser flare-meter (FM-500, KOWA) on day 4-5 postoperatively was significantly greater in the diclofenac group than with flurbiprofen (p = 0.022). Patients treated with diclofenac had significantly less burning and stinging than patients on flurbiprofen and indomethacin on postoperative days 4-5 (p < 0.0001) and 12-14 (p = 0.001). Diclofenac sodium appears to be more potent than flurbiprofen in controlling intraocular inflammation after cataract surgery, while having better local tolerance than flurbiprofen or indomethacin.

A 29-year-old Hispanic man who had bilateral radial keratotomy (RK) and astigmatic keratotomy (AK) in his right eye 1 year previously went swimming in a lake. He subsequently developed foreign-body sensation and pain with a gradual decrease in vision over the following 5 weeks, despite treatment with ciprofloxacin hydrochloride (Ciloxan) and diclofenac sodium (Voltaren). The patient sought a second opinion. On examination, best corrected visual acuity was 20/40 in the right eye and 20/20 in the left. Slitlamp examination revealed mild conjunctival and scleral injection and a 3.5 mm diameter stromal infiltrate densest at the edges (Figure 1). The infiltrate involved one RK and one AK incision with gaping of both, approximately 90% depth incisions (Figure 2). The anterior chamber was deep and quiet. Examination was otherwise unremarkable. The cornea was scraped, but the smears were negative. The Ciloxan and Voltaren were stopped, and scopolamine four times a day was started. Cultures for aerobic, anaerobic, fungal, acid-fast bacilli, and Acanthamoeba were performed but showed no growth in the following week. Except for vascular ingrowth, there was no change in the appearance of the microbial keratitis during this week. An incisional biopsy and rescraping were performed, but there was again no growth of micro-organisms and no change in the microbial keratitis in the following 4 days. How would you manage this patient at this time?
