Objective: lens subluxation can lead to vision loss, visual distortion, also can cause secondary glaucoma, retinal detachment and other complications, surgical treatment is more complex and difficult, traditional large incision surgery unsatisfactory visual recovery, surgery complications lack of long recovery time. With the maturing of ophthalmic surgical equipment and surgical techniques continue to improve, as well as new surgical technology in recent years, the introduction of new material, so that the development of modern lens subluxation surgery toward minimally invasive surgery direction postoperative visual function improved significantly, greatly reduce surgical complications and shorten recovery time, thereby expanding the indications for surgery for lens subluxation treatment. This article aims to explore different ways of modern treatment techniques for small incision surgery in the treatment of lens subluxation and postoperative clinical efficacy observed. Methods: The retrospective study from August 2008 to October 2009, the Second Affiliated Hospital of Dalian Medical University due to lens subluxation line small incision lens surgery treatment in a group of patients with 20 patients (21). Lens dislocation in the range of in 1/3-2 one quadrant, nine of dislocation range of 1-2 quadrants, which above the dislocation 5, nasal dislocation 2, below the dislocation 2; the Dislocation range of 12 lt; a quadrant. Following two kinds of surgical methods were used: 1. The lens dislocation Range lt; the quadrants and dislocation range below 1-2 quadrants dislocation 14 using simple phacoemulsification lens suction joint of lens subluxation range and location foldable posterior chamber intraocular lens implantation; 2. the lens dislocation range 1-2 quadrants remaining seven phacoemulsification lens suck addition to joint capsular tension ring and a foldable posterior chamber intraocular lens implantation (which iris part of a range of defects and dislocation the larger joint iris retractors pouch fixed). Were observed after the best corrected visual acuity, intraocular pressure, intraocular lens position, and surgical complications. Results: All 21 were successfully completed surgery, an artificial lens implanted in the capsular bag. 3 months after surgery best corrected visual acuity improved significantly, and the difference was statistically significant (t = -10.45, P lt; 0.01); improve best corrected visual acuity between the two surgical methods, the difference was not statistically significant (t 1.74, P gt; 0.05). Significantly lower postoperative IOP compared with the preoperative difference was statistically significant (t = 2.84, P lt; 0.05); reduction of intraocular pressure between the two surgical methods, the difference was not statistically significant (t = -0.87 , P gt; 0.05). Two surgical methods intraocular lens anteroposterior rate difference was not statistically significant (Fisher's exact, P = 0.75 gt; 0.05). Two surgical methods were no serious or special complications. The postoperative reaction between the two surgical methods, the difference was not statistically significant (Fisher exact test, P corneal edema = 0.44, P iris inflammatory response = 0.56, P high IOP = 0.25, P posterior capsular opacification = 0.57, P gt; 0.05). Conclusion: the lens subluxation modern surgical treatment, according to the specific circumstances of the patients and doctors to select the most appropriate minimally invasive surgical approach, and make full use of the new technology of modern ophthalmology, is conducive to the improvement of visual function in patients with surgery and intraoperative and anti-disease after reduction.
