Introduction: The combined phaco-sclerectomy supplanted the phaco-trabeculectomy. With equivalent results on intraocular pressure, it entails fewer complications. We present our experience.

Materials and method: 55 eyes of 42 patients, including 17 women and 25 men, with both chronic glaucoma and  cataract, were operated between June, 98 and May, 2000. The average age was of 77,5 years +/-10. The preoperative intraocular pressure varied around 21 mmhg +/- 8,5 with a number of 2 or 3 glaucoma medications. The visual acuity before surgery did not overtake 20/63. All the patients had a phaco-emulsification associated to a deep sclerectomy under topical anaesthesia (Tetracaпne *)  

Results: During the post-operative follow-up, the pressure was of 15 mmHg. At least 96 % of the patients had an intraocular pressure lower than 21 mmHg. The intraocular average pressure was 21 mmHg under  bi or tri - therapy before surgery. Among these cases of normalization, 3 cases required the reintroduction of glaucoma medications. In the early post-operative, we noted 3 choroidal detachments (effusion) by hypotony and 4 Neodymium:YAG laser goniopunctures have been performed after micro-perforation. As for visual outcomes, the average acuity was around 20/20 for an average of 20/63 in preoperative. 

Conclusion: Realized under topical anaesthesia in ambulatory surgery, it represents a real comfort, for the surgeon as well as for the patient. The deep sclerectomy is approachable but requires well trained surgeons. The results after 2  years are stable but sometimes glaucoma medications are required.
