PURPOSE: Open-sky cataract extraction during triple procedure can be associated with higher risk of complications owing to the missing counterbalance by the cornea. Herein, we present a fast and easy technique for visualization of the anterior chamber and the lens in eyes with opaque corneas planed for triple procedure. MATERIALS AND METHODS: Four patients with corneal oedema due to Fuchs' endothelial dystrophy and cataract underwent triple procedure. As the anterior chamber view was limited, the central 7.0 mm of the cornea was marked. Then, 60-80% of the corneal thickness was removed by lamellar dissection and filled with hydroxypropylmethylcellulose. Continuous curvilinear capsulorhexis (CCC) and phacoemulsification with intraocular lens implantation through a corneoscleral tunnel were then performed and at the end the remaining corneal tissue was excised and the donor tissue fixed with a single running continuous suture. RESULTS: Lamellar corneal dissection enhances the anterior chamber view and CCC can be performed under stable anterior chamber condition. Phacoemulsification via sclerocorneal tunnel could be easily performed under good anterior chamber view in all cases. The operation time was 60-75 min in all cases. CONCLUSION: Lamellar corneal dissection in opaque corneas before cataract extraction is a useful technique for enhancing anterior chamber view in cases of triple procedure.
PURPOSE: To describe the characteristics of a new artificial anterior chamber (MALKS, Loktal, São Paulo, Brazil). METHODS: Characteristics analysis and description of a new artificial anterior chamber MALKS (Micro automated lamellar keratoplasty system). RESULTS: MALKS is composed of eight parts: a) artificial chamber; b) cornea's fix ring; c) nut to join the cornea's fix ring; d) rail and adjuster of lamellar diameter; e) flatteners, to pre-determine lamellar diameter; f) infusion system, that allows the digital objective peroperative control of the intracameral pressure; g) automated microkeratome, and h) marker. CONCLUSION: MALKS uses the same automated microkeratome developed for LASIK, can allow corneal lamella obtention with predetermined thickness and diameter, as well as the digital objective peroperative control of the intracameral pressure. This new artificial anterior chamber can be an important tool for superficial and endothelial keratoplasty.
