[Interface diffuse keratitis].

Diffuse interface keratitis is a new clinical entity. It is becoming significantly more common due to the increasing of laser assisted in situ keratomileusis (LASIK) procedures. The knowledge we have about this uncommon but potentially sight-threatening complication is expanding. It appears in the early postoperatory LASIK, even in well-executed procedures. In this review we present an updated strategy for the diagnose and treatment of this syndrome, based on our own experience and an updated literature review. Early identification, evaluation, staging, and appropriate intervention, may help preventing visual loss associated with this entity.

[Retinal detachment surgery after refractive surgery].

PURPOSE: To analyze the characteristics of retinal detachments (RD) in myopic patients who underwent different kinds of refractive surgery (RS). Modifications in patient eyes deriving from RS and how it hindered surgery for treating RD, was also studied. MATERIAL AND METHODS: 14 (6 female/8 male) patients with RD after having been treated with RS (laser assisted in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), radial keratotomy (RK) and phakic anterior chamber lenses). RD was treated by scleral surgery and in two cases by vitrectomy after first RD surgery. RESULTS: 12 RD cases showed slight modification over previous refraction. In 2 cases vitrectomy was necessary since proliferative vitreoretinopathy was evidenced. The appearance of RD cases did not increase after PRK, RK or LASIK. RS did not hinder RD surgery. RD appearance in patients with anterior chamber lenses was higher, with severe difficulty in peripheral exploration and in performing RD surgery. CONCLUSION: After PRK, RK and LASIK, RD surgery does not show more difficulty, while after anterior chamber intraocular lenses implantation there is an increased difficulty for RD surgery.

[Alterations in blood-aqueous barrier after PRK].

PURPOSE: To evaluate alterations in the blood-aqueous barrier after photorefractive keratectomy with excimer laser. METHODS: Aqueous flare was evaluated using the Kowa FC 1000 laser flare meter in a total of 22 eyes which underwent photorefractive keratectomy. Myopia ranging was from -5,87 to -1,25 (-3,73+/-1,44, mean+/-SD). Anterior chamber inflammation was measured preoperatively and 1, 3, 7 and 15 days, and 1 and 3 months postoperatively using the flare mode of a laser flare-cell meter. All eyes received topical 0.25% fluorometholone drops in decreasing dosage. RESULTS: Anterior chamber flare values were not significantly different from those found preoperatively. CONCLUSIONS: Our study shows that photorefractive keratectomy in low myopia does not induce an inflammatory response in the anterior chamber.

Astigmatism induced by intrastromal corneal suture after small incision phacoemulsification.

PURPOSE: To evaluate the course of astigmatic evolution and complications after clear corneal incisions using an intrastromal corneal suture. SETTING: Instituto Oftalmologico de Alicante, University of Alicante, Spain. METHODS: Eighty eyes of 62 patients had endocapsular phacoemulsification. A foldable intraocular lens was implanted through a 4.0 mm clear corneal incision. A 10-0 nylon intrastromal corneal suture was used in all eyes. Change sin corneal astigmatism were calculated by vector analysis; follow-up was 6 months. Early and late suture-related complications were also evaluated. RESULTS: Mean induced cylinder was 1.25 diopters (D) +/- 1.24 (SD) with the wound 1 day postoperatively and 0.19 +/- 0.81 D against the wound at 6 months. There were no incision- or suture-related complications postoperatively. CONCLUSION: Use of the intrastromal corneal suture led to astigmatically neutral closure of multiplanar corneal incisions.

Total anterior capsule closure after silicone intraocular lens implantation.

An 84-year-old man with a nuclear cataract had phacoemulsification, continuous curvilinear capsulorhexis, and implantation of a silicone intraocular lens. Two months later, the patient had vision loss and severe anterior capsule fibrosis, leading to complete posterior chamber lens encapsulation. After a capsular opening was created with a neodymium:YAG laser, visual acuity returned to the preoperative level of 20/30.

Intrastromal corneal suture for small incision cataract surgery.

Proper wound closure is important in preventing postoperative endophthalmitis. We developed an intrastromal corneal suture technique that uses some principles of the running, locked, intradermal suture for light-tension skin wounds. It achieves close approximation of the wound edges, reduces postoperative wound care and the risk of wound infection in clean surgical wounds, and obviates suture removal. It may also help prevent endophthalmitis and early against-the-rule astigmatism without the complications associated with external suture exposure.

[Treatment of corneal edema using saturation of free radicals].

We report on the results obtained in the treatment of inflammation of the cornea by means of the saturation of free radicals, using chemiluminescence. The experiment was conducted on the Alloxan model of corneal inflammation caused by the freeing of free radicals in the stroma. We compared the action of steroidal and non-steroidal antiinflammatory substances, and also specific saturators of free radicals.
