Abstract. Purpose:To report causes of luxation and subluxation of crystalline lens. Cases:This retrospective study was made on 62 eyes of 54 patients who received surgery during the foregoing 93 months. Luxation and subluxation were present in 31 eyes each. The series comprised 37 and 17 females. The age averaged 58 years. Results:Lens luxation was due to high myopia 7 eyes, blunt trauma 7 eyes, Marfan syndrome 3 eyes, laser iridotomy 3 eyes, pseudoexfoliation one eye, and unknown 10 eyes. Subluxation was due to blunt trauma 6 eyes, Marfan syndrome 2 eyes, laser iridotomy 3 eyes, pseudoexfoliation 2 eyes, atopic dermatitis 2 eyes, and unknown 16 eyes. Vitrectomy with pars plana lensectomy was performed on 61 eyes. Intraocular lens was implanted in 45 eyes. Conclusion:Blunt trauma was the frequent cause for lens luxation and subluxation. Due attention is needed for laser iridotomy as a possible cause for dislocation of the lens.
