An intraocular lens adapted to be inserted inwardly into a capsular sac, comprising: an optic portion including a first optic body whose central region has a smaller thickness than a circumference of the central region and a second optic body (121 b) coupled to the first optic body and whose central region has the same or higher thickness as/than the first optic body; and a haptic portion including a connection bar coupled to the optic portion and first support bar coupled to a circumference of the connection bar to be in contact with an inner surface of the capsular sac when inserted into the capsular sac, wherein the first support bar is a structural body that is extended along an end of the connection bar, and includes a first face coming in contact with the inner surface of the capsular sac in at least one point when inserted into the capsular sac, and a second face arranged opposite to the first face, and that the first face is provided at a length as much as 3/4 to 3 times of a length of a region where a zonule of Zinn is coupled to an outer surface of the capsular sac in a section where the first support bar is cut along a virtual plane in a visual axis direction of an eye lens when inserted into the capsular sac, the first face has a first extended length from one end portion to the other end portion in the section where the first face is cut along the virtual plane in the visual axis direction of the eye lens, the second face has a second extended length from one end portion to the other end portion in the section where the second face is cut along the virtual plane in the visual axis direction of the eye lens, and the second extended length of the second face is smaller than or identical to the first extended length of the first face and the second extended length of the second face is longer as much as 0.4 to 1 times than the first extended length of the first face, characterized in that the first face has an anterior portion and a posterior portion which corresponds respectively to an anterior capsule and a posterior capsule of the capsular sac when inserted into the capsular sac, divided by an equator of the capsular sac, wherein the equator is a vertical direction relative to the visual axis direction of the eye lens, wherein the anterior portion has a larger curvature than the posterior portion in the section where the first face is cut along the virtual plane in the visual axis direction of the eye lens, the first extended length has a length of 2 to 8.4 mm. an optic portion including a first optic body whose central region has a smaller thickness than a circumference of the central region and a second optic body (121 b) coupled to the first optic body and whose central region has the same or higher thickness as/than the first optic body; and a haptic portion including a connection bar coupled to the optic portion and first support bar coupled to a circumference of the connection bar to be in contact with an inner surface of the capsular sac when inserted into the capsular sac, wherein the first support bar is a structural body that is extended along an end of the connection bar, and includes a first face coming in contact with the inner surface of the capsular sac in at least one point when inserted into the capsular sac, and a second face arranged opposite to the first face, and that the first face is provided at a length as much as 3/4 to 3 times of a length of a region where a zonule of Zinn is coupled to an outer surface of the capsular sac in a section where the first support bar is cut along a virtual plane in a visual axis direction of an eye lens when inserted into the capsular sac, the first face has a first extended length from one end portion to the other end portion in the section where the first face is cut along the virtual plane in the visual axis direction of the eye lens, the second face has a second extended length from one end portion to the other end portion in the section where the second face is cut along the virtual plane in the visual axis direction of the eye lens, and the second extended length of the second face is smaller than or identical to the first extended length of the first face and the second extended length of the second face is longer as much as 0.4 to 1 times than the first extended length of the first face, characterized in that the first face has an anterior portion and a posterior portion which corresponds respectively to an anterior capsule and a posterior capsule of the capsular sac when inserted into the capsular sac, divided by an equator of the capsular sac, wherein the equator is a vertical direction relative to the visual axis direction of the eye lens, wherein the anterior portion has a larger curvature than the posterior portion in the section where the first face is cut along the virtual plane in the visual axis direction of the eye lens, the first extended length has a length of 2 to 8.4 mm.
