【摘要】：目的： 應(yīng)用計算機隨機點立體視檢查系統(tǒng)檢測白內(nèi)障術(shù)后立體視覺功能,探討該新型檢測手段的可行性和實用性；并分析比較植入不同類型的人工晶狀體的患者的立體視覺功能。 方法： 應(yīng)用計算機隨機點立體視檢查圖(random-dot stereogram, RDS)對78例白內(nèi)障超聲乳化合并人工晶狀體植入術(shù)后的患者進行立體視覺功能的檢測,檢測時分別按照3種不同密度和4種不同隨機點大小設(shè)定檢查圖,并比較檢查結(jié)果的差異。此外,將受試者按照人工晶狀體的類型分為“單焦組”(42人,植入美國ALCON公司單焦人工晶狀體,型號Acrysof SN60WF,非球面設(shè)計)和“多焦組“(36人,植入美國ALCON公司多焦人工晶狀體,型號Restor+3D SN6AD1,非球面漸進衍射型多焦點設(shè)計),比較這兩組患者的立體視覺功能的差異。 結(jié)果： 在術(shù)后三個月,(1)多焦組的裸眼中距離視力和裸眼近距離視力均顯著好于單焦組,兩組的裸眼遠距離視力沒有統(tǒng)計學(xué)差異；(2)當隨機點的大小固定而密度不同時,患者立體視銳度檢查結(jié)果沒有統(tǒng)計學(xué)差異；(3)當隨機點密度相同而大小不同時,患者立體視銳度檢查結(jié)果的差異存在統(tǒng)計學(xué)意義；(4)多焦組立體視銳度顯著優(yōu)于單焦組。 結(jié)論： 計算機隨機點立體視圖是一種可靠的測量立體視功能的方法,可以用于白內(nèi)障患者術(shù)后立體視覺功能的檢測。立體視覺功能可能牽涉到復(fù)雜的神經(jīng)學(xué)機制,視力可能并不是決定白內(nèi)障術(shù)后患者立體視覺功能優(yōu)劣的最主要因素。
[Abstract]:Objective: The stereoscopic vision function after cataract surgery was detected by the computer random spot stereoscopic examination system, and the feasibility and practicability of the new method were discussed. The stereoscopic vision of patients with different types of intraocular lens implantation was analyzed and compared. Methods: Random dot stereogram was examined by computer random dot stereopsis. RDS was performed in 78 patients with cataract after phacoemulsification and intraocular lens implantation. According to 3 different density and 4 different random spot size, the examination chart was set up, and the difference of examination results was compared. In addition, the subjects were divided into "single focus group" and "single focus group" according to the type of intraocular lens. Implantation of ALCON single focus intraocular lens, model Acrysof SN60WF, aspherical design) and "multi-focus group" 36 people. Implanted ALCON multi-focal intraocular lens, model Restor 3D SN6AD1, Aspheric progressive diffraction multi-focus design. To compare the difference of stereoscopic vision function between the two groups. Results: At 3 months after operation, the median visual acuity and close visual acuity of the multi-focus group were significantly better than that of the single-focus group, and there was no significant difference in the distance visual acuity between the two groups. 2) when the size of random spot was fixed and the density was different, there was no statistical difference in stereopsis acuity. 3) when the random spot density was the same and the size was different, the difference of stereopsis acuity was statistically significant. The stereoscopic acuity of multi-focus group was significantly better than that of single-focus group. Conclusion: The computer random spot stereoscopic view is a reliable method to measure stereoscopic function, which can be used to detect the stereoscopic function of cataract patients after surgery. Stereoscopic vision may involve complicated neurologic mechanism. Visual acuity may not be the most important factor in determining stereo vision function after cataract surgery.
