术前行视力、眼压、B超、UBM、角膜内皮细胞计数等常规检查,并散瞳检查晶状体脱位部位及范围。采用德国蔡司非接触光学相干生物测量(IOL-Master)测量角膜曲率、眼轴长度及计算人工晶状体度数。所有患者术前3 d予左氧氟沙星滴眼液点眼4次/日预防感染,术前1 h予复方托吡卡胺滴眼液散瞳,每15 min 1次,共4次。
Figure 1 Case 1: A 54-year-old male patient with subluxation of the left lens underwent phacoemulsification with scleral suspension of the intraocular lens
(A) The upper suspensory ligament is ruptured and the lens is deflected downward. (B) A viscoelastic agent is injected below the lens to lift the lens upward. (C) Suture 1 is inserted from the 8 point position to the 2 point position using a 2 mL syringe needle. (D) Leave the end of suture 1 outside the inlet and tie the end of suture 2. (E) Pull the knot toward the anterior chamber and pull out the knot from the main incision, and cut the end of suture 1. (F) Tie off the end of suture 1 2mm from the distal end of the front loop for the IOL. (G) Push the IOL into the anterior chamber. (H) Place the IOL behind the lens, leaving the posterior loop outside the primary incision. (I) Tie off the end of the suture 22mm from the distal end of the posterior IOL loop. ( J) Place the IOL completely behind the lens.(K) Move the lens to orthotopic position. (L) Hold the lens in position with 3 iris hooks. (M)Phacoemulsification of the lens. (N) Remove the iris hook. (O) Cut the remaining suspensory ligament residual suspensory ligament and remove the capsular pouch completely. (P) Cut through the anterior vitreous. (Q) The suture needle1 was inserted from the original conjunctival outlet, and Z-shaped suture was performed in the superficial sclera. (R) Needle2 was used to suture the opposite side of the sclera in the same way, alternating the sutures symmetrically on both sides to center the IOL. (S) Suture
main incision.

Figure 2 Case 2: A 53-year-old female patient with subluxation of the right lens underwent phacoemulsification with scleral suspension of the intraocular lense
(A)The lower suspensory ligament is broken, and the lens is upward deviated. (B)The tail of suture1 is attached to the anterior loop of the IOL. (C)The needle1 is inserted from the main incision to the 3 o'clock position. (D)The IOL is pushed into the anterior chamber of the eye. (E)The posterior IOL loop was left outside the primary incision, and the tail of suture 2 was tied to the rear IOL loop. (F)Using the irrigation cannula, the end of needle2 is retracted from the primary incision to the lateral incision. (G)Needle2 is inserted from the lateral incision to the 9 o'clock position. (H)IOL suspension was preliminarily completed. (I,J)Gently press down on the IOL and place it behind the lens. (K)Position the lens with an iris restorer through an incision in the plana of the ciliary body. (L)Superficial scleral Z suture was performed at 9 o 'clock with needle2. (M)The superficial scleral Z suture was performed at 3 o 'clock with needle1, , and IOL was initially fixed. (N)Posterior continuous curvilinear capsulorhexis. (O)Phacoemulsification of the lens. (P)Aspiration of the lens cortex. (Q)Cut the residual suspensory ligament and remove the capsular pouch completely. (R)Cut the anterior vitreous. (S)Complete the remaining steps of the Z suture. (T)Suture main incision.
