Abstract
We thank Drs. Chung and Lai for their interest in our work. They raise a valid concern with the 2-site phacotrabeculectomy technique, warning of a possible mechanism of extraocular fluid inflow after using clear corneal incisions in the cataract wound site. Because these eyes are more likely to experience a low postoperative intraocular pressure, events may be somewhat similar to those described in our experimental study. Risk of postoperative endophthalmitis may, at least hypothetically, be increased in this group of patients. Inflow of ocular surface fluid through clear corneal cataract incisions: A laboratory modelAmerican Journal of OphthalmologyVol. 139Issue 3PreviewIn the article by Sarayba and associates,1 the authors demonstrated inflow of India ink into the anterior chamber of fresh human donor globes through unsutured clear corneal incisions when either external manual pressure was applied or when the intraocular pressure (IOP) was lowered to 5 mm Hg. This suggested a possible way of pathogens in the extraocular fluid getting into the anterior chamber causing endophthalmitis. They also showed that no dye gained access into the eye in the presence of a suture. Full-Text PDF
